2-propanoyl-3-(4-isopropylphenyl)-tropane 2-propanoyl-3-(4-isopropylphenyl)-tropane 2-propanoyl-3-(4-isopropylphenyl)-tropane (wf-31, pit) is a cocaine analogue which acts as a serotonin-norepinephrine-dopamine reuptake inhibitor (sndri). research shows wf-31 to be approximately ten times more potent than cocaine at binding to the serotonin transporter and at inhibiting its reuptake. 2-propanoyl-3-(4-isopropylphenyl)-tropaneidentifiers iupac name 2-propanoyl-3-(4-isopropylphenyl)-tropane pubchem cid44458747chemspider23121202chemblchembl278122chemical and physical dataformulac20h29nomolar mass299.458 g·mol−13d model (jsmol)interactive image smiles ccc(=o)c1c2n(c)c(cc2)cc1c3ccc(c(c)c)cc3 inchi inchi=1s/c20h29no/c1-5-19(22)20-17(12-16-10-11-18(20)21(16)4)15-8-6-14(7-9-15)13(2)3/h6-9,13,16-18,20h,5,10-12h2,1-4h3key:bvsomkyawfjcth-uhfffaoysa-n (verify)
