Chemical Composition & Structure

EPT (systematic name: N-Ethyl-N-propyltryptamine, also known as ethylpropyltryptamine) is a synthetic indolealkylamine belonging to the tryptamine chemical family. The fumarate salt form features asymmetric N-alkyl substitution with an ethyl group and propyl group on the side chain amine nitrogen. The molecular formula C₁₅H₂₂N₂ · C₄H₄O₄ yields a molecular weight of 274.35 g/mol for the fumarate salt.

As a structural analog positioned between MET (N-ethyl-N-methyltryptamine) and DPT (N,N-dipropyltryptamine), EPT offers unique insights into structure-activity relationships. The propyl substitution extends the alkyl chain length compared to MET, making it valuable for studying how N-alkyl chain length affects receptor binding affinity and pharmacological properties. The fumarate salt provides enhanced stability and improved handling characteristics compared to the freebase form.

Research Applications

biosynlab EPT Fumarate Powder serves as standardized reference material for:

• Serotonin receptor pharmacology (5-HT₂A, 5-HT₂C, 5-HT₁A, 5-HT₇)
• Structure-activity relationship (SAR) studies
• Comparative binding affinity assays with MET, DPT, and other dialkyltryptamines
• Chain-length dependency research in N-alkyltryptamines
• Metabolism and pharmacokinetic studies
• Analytical method development (HPLC, GC-MS, LC-MS/MS)
• Forensic toxicology reference standards
• Receptor subtype selectivity investigations

Researchers utilize EPT alongside related dialkyltryptamines including DMT, DET, DPT, MET, and comparative studies with 4-substituted and 5-substituted tryptamine analogs to advance understanding of how N-alkyl chain length influences pharmacological activity and receptor
