Product Description
(2S)-1-(Chloroacetyl)-2-pyrrolidinecarbonitrile is a high-purity chiral intermediate essential for the pharmaceutical industry. This off-white to light yellow solid is a primary building block in the synthesis of DPP-4 inhibitors, specifically the anti-diabetic medication Vildagliptin. Its precise (2S)-configuration ensures the correct stereochemistry required for biological activity. Engineered for high reactivity and stability, it allows for efficient coupling with various amines. This intermediate is indispensable for manufacturers focused on high-yield production of advanced pharmaceutical ingredients (APIs) and specialized heterocyclic synthesis.
