alpha-Cyclopentylmandelic acid, (+)

Its uses include helping to introduce the required chiral configuration into the molecule, which is a soft anticholinergic agent (a type of glycopyrrolate analog) designed for the treatment of hyperhidrosis. (+)-α-Cyclopentylmandelic acid, also known as (R)-α-cyclopentylmandelic acid (CAS 427-49-6), is a key chiral intermediate employed to synthesize sofpironium bromide.
