(2S,4S)-4-Cyanopyrrolidine-2-carboxylic acid

3-Amino-5-methylpyridine-2-carbonitrile

Pyridine-based pharmaceutical intermediate

(2S,4S)-4-Cyanopyrrolidine-2-carboxylic acid is a chiral building block used in pharmaceutical manufacturing. It contains a pyrrolidine ring with nitrile and carboxylic acid functional groups, making it suitable for constructing molecules that modulate dipeptidyl peptidase-4 (DPP-4) activity in research settings.
