LSZ L-tartrate Pure

Buy LSZ L-tartrate Pure Research Chemical Online – USA, Europe & Worldwide

RChems EU is pleased to present LSZ L-tartrate Pure, a premium-grade research chemical designed for advanced pharmacological and neurochemical investigations. LSZ (Lysergic acid 2,4-dimethylazetidide) is a lysergamide analogue that has attracted scientific interest due to its distinct structural modification at the amide nitrogen—specifically, the introduction of a 2,4-dimethylazetidine ring. Unlike the more common diethylamide (LSD) or ethylcyclopropyl (1cP-LSD) variants, LSZ offers researchers a unique tool for exploring steric and electronic effects on serotonin 5-HT2A receptor binding. Our LSZ L-tartrate Pure is supplied as a stable, non-hygroscopic salt, enhancing handling accuracy and long-term storage stability. Whether you need to buy LSZ L-tartrate for receptor binding assays, structure-activity relationship (SAR) studies, or comparative metabolic profiling, RChems EU delivers 99% pure LSZ with full analytical transparency. As a trusted global supplier, we ensure every order arrives via fast worldwide delivery in discreet, unmarked packaging.

Product Specifications

Applications & Usage

LSZ L-tartrate Pure is intended for legitimate scientific research only. Typical applications include:

• Receptor Binding Assays: Quantifying affinity (Ki) at serotonin 5-HT2A, 5-HT2C, and 5-HT1A receptors using radioligand displacement (e.g., [³H]-ketanserin or [¹²⁵I]-DOI).
• Functional Assays: Measuring G-protein coupling, IP3 accumulation, or β-arrestin recruitment in transfected cell lines (e.g., CHO-K1 or HEK-293 expressing human 5-HT2A receptors).
• Metabolic Stability Studies: Investigating phase I and phase II metabolism using liver microsomes or hepatocytes—comparing LSZ’s metabolic profile to LSD and other lysergamides.
• Structure-Activity Relationship (SAR) Research: Understanding how the 2,4-dimethylazetidine ring influences receptor subtype selectivity and intrinsic activity.
• Analytical Reference Standard: Use as a certified reference material for LC-MS/MS method development in forensic or toxicology laboratories.
• Behavioral Pharmacology: Approved animal studies examining head-twitch response (HTR) or prepulse inhibition of startle (subject to institutional ethics approval).

When researchers buy LSZ L-tartrate for research, the L-tartrate salt is preferred over freebase because it dissolves readily in phosphate-buffered saline (PBS) and cell culture media without requiring acidic conditions that might degrade the compound. This ensures reproducible results across multiple experiments and laboratories.

Purity & Testing

At RChems EU, we do not rely on manufacturer-provided certificates alone. Every batch of LSZ L-tartrate Pure undergoes independent, multi-modal analytical characterization before being released for sale:

1. High-Performance Liquid Chromatography with Diode Array Detection (HPLC-DAD):
   • Quantifies purity at ≥99% across three wavelengths (220 nm, 254 nm, 310 nm).
   • Detects related substances including iso-LSZ, lysergic acid, and unreacted intermediates (each <0.5%).
2. Nuclear Magnetic Resonance Spectroscopy (¹H NMR and ¹³C NMR):
   • Confirms the expected proton and carbon environments.
   • Validates the 1:0.5 stoichiometry of LSZ freebase to L-tartaric acid.
   • Rules out residual solvents (ethyl acetate, DCM, hexane) above ICH limits.
3. High-Resolution Mass Spectrometry (HRMS-ESI):
   • Confirms the exact mass of the [M+H]⁺ ion at m/z 379.2487 (freebase) and tartrate counterion signature.
4. Karl Fischer Titration: Ensures residual water content <1%, confirming the non-hygroscopic nature of the salt.
5. Heavy Metals Screening (ICP-MS): Certifies that lead, arsenic, cadmium, and mercury are below detectable limits (<1 ppm).

When you buy 99% pure LSZ L-tartrate from RChems EU, you receive a COA summarizing all five tests. This transparency ensures your research findings are not confounded by impurities or misidentified compounds—a critical advantage for publication in peer-reviewed journals.

Safety & Handling Guidelines

FOR LABORATORY RESEARCH USE ONLY. NOT FOR HUMAN OR ANIMAL CONSUMPTION.

• Personal Protective Equipment (PPE): Always wear nitrile gloves, a lab coat, and safety goggles when handling LSZ L-tartrate powder.
• Engineering Controls: Use a certified chemical fume hood or glovebox when weighing or preparing solutions to minimize airborne particle exposure.
• Surface Decontamination: Clean spills with 10% bleach solution (degrades lysergamides) followed by ethanol.
• Storage: Store in original amber glass vials at 2–8°C (do not freeze). Avoid repeated opening; use desiccant if storing long-term.
• Incompatibilities: Avoid strong oxidizers, strong acids, and direct sunlight.
• Disposal: Follow institutional hazardous waste protocols for controlled substance analogues.

FAQ Section

1. What is LSZ L-tartrate used for in research?

LSZ (Lysergic acid 2,4-dimethylazetidide) is a semi-synthetic ergoline used to study serotonin 5-HT2A receptor pharmacology. The LSZ L-tartrate Pure form is specifically used in receptor binding assays, functional GPCR studies, metabolic stability experiments, and SAR comparisons with LSD, 1P-LSD, and ALD-52. The L-tartrate salt improves aqueous solubility, making it easier to prepare accurate solutions for cell-based assays.

2. Is LSZ L-tartrate legal to buy online?

The legal status of LSZ for research varies by country. In the United States, LSZ is not explicitly listed in Schedule I, but the Federal Analogue Act may apply if intent for human consumption is demonstrated. In many European nations (e.g., Germany, UK, France), LSZ exists in a regulatory gray area as a non-scheduled analogue. RChems EU sells LSZ L-tartrate strictly as a research chemical. Buyers must independently verify local laws. We do not ship to countries with blanket bans on lysergamides.

3. How discreet is your shipping for LSZ L-tartrate?

Extremely discreet. Your LSZ L-tartrate Pure order arrives in plain, unbranded packaging with no company logo and no chemical name anywhere on the exterior. The return address uses a generic name (e.g., “LC Fulfillment”). Inside, the product is vacuum-sealed in an opaque pouch. Customs declarations use vague, non-alarming descriptions such as “Laboratory reagent sample” or “Inert solid for analysis.” This ensures complete privacy for academic and industrial researchers.

4. What is the exact purity level of your LSZ L-tartrate?

Our LSZ L-tartrate Pure consistently tests at ≥99% purity by HPLC-DAD (area normalization at 254 nm). The remaining <1% consists of trace residual solvents (e.g., ethanol, <0.5%) and water (Karl Fischer <1%). No undeclared adulterants, cutting agents, or isobaric impurities are present. The compound is supplied as the authentic hemi-L-tartrate salt (1:0.5 molar ratio), confirmed by NMR integration.

5. How do you test the purity of LSZ L-tartrate?

We perform five independent tests: HPLC-DAD (purity ≥99%), ¹H and ¹³C NMR (structural confirmation and salt ratio), HRMS (exact mass verification), Karl Fischer (water content), and ICP-MS (heavy metals). A Certificate of Analysis summarizing all results is available by batch number. This rigor ensures that when you buy LSZ L-tartrate from RChems EU, your research is based on a fully characterized compound.

6. Can I track my LSZ L-tartrate shipment internationally?

Yes. All orders receive a discrete tracking number via email. You can monitor progress from our warehouse through your local delivery hub. The tracking portal does not disclose product details—only “Shipment in transit” and estimated dates. For maximum privacy, we recommend using a institutional address or a trusted commercial receiving point.

7. How should I store LSZ L-tartrate for long-term research?

Store the LSZ L-tartrate Pure in its original amber glass vial inside a refrigerator (2–8°C) with the cap tightly sealed. Add a desiccant packet to the outer container if storing for >6 months. Avoid repeated opening; allow the vial to reach room temperature before opening to prevent condensation. Do not freeze. Under these conditions, the compound remains stable for at least 18 months.

8. Why choose the L-tartrate salt over freebase LSZ?

The L-tartrate salt offers superior aqueous solubility (≥5 mg/mL in water vs. <0.1 mg/mL for freebase), non-hygroscopic handling (does not clump or absorb atmospheric moisture), and enhanced thermal stability. For researchers preparing stock solutions for cell culture or receptor assays, the salt form eliminates the need for acidic or organic solvents that could interfere with biological systems.
