Aminorex

4B-MAR (4-Bromo-4-methylaminorex) , also known as 4'-Bromo-4-methylaminorex, is a synthetic stimulant research chemical belonging to the substituted aminorex family. Structurally related to 4-methylaminorex, this brominated analog features a bromine atom at the 4-position of the phenyl ring, significantly altering its pharmacological profile as a monoamine releasing agent. The bromine substitution introduces distinct electronic and steric properties—larger and more polarizable than fluorine or chlorine—making it a critical tool for halogen SAR studies. RChems EU supplies 4B-MAR as a high-purity crystalline powder with verified 99%+ purity, ensuring reproducible results for in vitro neurotransmitter transporter assays, neuropharmacological investigations, and structure-activity relationship (SAR) studies across the complete halogenated aminorex series (F, Cl, Br).

4C-MAR (4-Chlorine-4-methylaminorex) is a synthetic stimulant research chemical belonging to the aminorex class. Structurally related to 4-methylaminorex, this chlorinated analog features a chlorine atom at the 4-position of the phenyl ring, significantly altering its pharmacological profile as a monoamine releasing agent. The chlorine substitution introduces distinct electronic and steric properties compared to its fluorine and bromine counterparts. RChems EU supplies 4C-MAR as a high-purity crystalline powder with verified 99%+ purity, ensuring reproducible results for in vitro neurotransmitter transporter assays, neuropharmacological investigations, and structure-activity relationship (SAR) studies across the halogenated aminorex series.
