4-AcO-MPT fumarate (4-acetoxy-N-methyl-N-propyltryptamine fumarate) is a synthetic tryptamine derivative featuring an acetoxy group at the 4-position of the indole ring and mixed methyl/propyl substitution on the terminal amine. As a structural analog of psilocin (4-HO-DMT), the 4-acetoxy group serves as a prodrug moiety that undergoes enzymatic hydrolysis to yield the active 4-hydroxy metabolite, making it a valuable tool for comparative metabolic and receptor studies. RChems EU supplies 4-AcO-MPT as a stable, crystalline fumarate salt with verified 99%+ purity, ensuring reproducible results for in vitro receptor binding assays, metabolic stability research, and neuropharmacological investigations.
