5-(2-methylaminopropyl)benzofuran (abbreviated 5-MAPB) is a synthetic entactogen of the substituted benzofuran class of chemicals, which are known to produce euphoric, entactogenic, stimulating and mildly hallucinogenic effects. These include such MDA-inspired substances as 5-APB, 6-APB and 5-EAPB, among others. 5-MAPB is the N-methylated form of 5-APB, analogously to how MDMA is the N-methylated form of MDA.

This compound is known for its stimulating, euphoric and entactogenic effects that is capable of acting a quasi-substitute for MDMA proper, which has resulted in its rise in popularity as a research chemical that is easily accessible through the use of online vendors.

5-MAPB is commonly found as the succinate and hydrochloride salt. The hydrochloride salt is 10% more potent by mass so doses should be adjusted accordingly.
