Glycopyrrolate is a powder that is freely soluble in water. The molecular formula is C 19 H 28 BrNO 3 , and the molecular weight is 398.33 g/mol. The structural formula is as follows: Glycopyrrolate contains two chiral centers (denoted by * in structure above) and is a racemate of a 1:1 mixture of the R,S and S,R diastereomers. The active moiety, glycopyrronium, is the positively charged ion of glycopyrrolate.
