4-HO-EPT fumarate

Price range: € 23,50 through € 336,00
Select options This product has multiple variants. The options may be chosen on the product page

4-HO-EPT fumarate (4-hydroxy-N-ethyl-N-propyltryptamine fumarate) is a synthetic tryptamine derivative featuring a hydroxy group at the 4-position of the indole ring and mixed ethyl/propyl substitution on the terminal amine. This symmetric di-alkyl substitution pattern (both chains are linear, two and three carbons respectively) distinguishes 4-HO-EPT from other 4-hydroxytryptamines and offers researchers a valuable tool for investigating how N-alkyl chain lengthening affects serotonin receptor pharmacology. RChems EU supplies 4-HO-EPT as a stable, crystalline fumarate salt with verified 99%+ purity, ensuring reproducible results for in vitro receptor binding assays and neuropharmacological investigations.
