diphenylprolinol diphenylprolinol diphenylprolinol (d2pm), or (r/s)-(±)-diphenyl-2-pyrrolidinyl-methanol, is a norepinephrine-dopamine reuptake inhibitor which is used as a designer drug. diphenylprolinolclinical dataatc codenonelegal statuslegal status de: npsg (industrial and scientific use only) uk: class b identifiers iupac name diphenyl(pyrrolidin-2-yl)methanol cas number22348-32-9 npubchem cid204386chemspider177034 yunii54u9un7hn4comptox dashboard (epa)dtxsid60944996 echa infocard100.118.791 chemical and physical dataformulac17h19nomolar mass253.345 g·mol−13d model (jsmol)interactive image smiles oc(c1ccccc1)(c2ccccc2)c3nccc3 inchi inchi=1s/c17h19no/c19-17(16-12-7-13-18-16,14-8-3-1-4-9-14)15-10-5-2-6-11-15/h1-6,8-11,16,18-19h,7,12-13h2 ykey:ogcgxugbdjgffy-uhfffaoysa-n y ny (what is this?) (verify) pharmacology the dextrorotary (r)-(+)-enantiomer is the more pharmacologically active, although a variety of related derivatives have been studied. side effects including chest pain (suggestive of possible cardiovascular toxicity) have been seen following recreational use of diphenylprolinol, although it was combined with glaucine in a party pill product, thus making it impossible to say for certain which drug was responsible. other uses diphenylprolinol can be used to prepare the chiral cbs catalyst, which is used for enantioselective organic synthesis.
