Oxiracetam is substituted with a further hydroxy team at R4, and that is a chiral center for your molecule. Oxiracetam is presumably generated as a racemate of its enantiomers. Oxiracetam is structurally analogous to piracetam, which lacks the R4 hydroxy substitution of oxiracetam.DISCLAIMER: PW's dosage details is collected from buyers and methods
