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.
Product Features
- Key API Intermediate: Specifically designed for the synthesis of Vildagliptin and other related DPP-4 inhibitors for diabetes management.
- High Chiral Purity: Maintained with strict enantiomeric control (typically ee over 99%) to ensure the efficacy of the final pharmaceutical product.
- Optimal Reactivity: The chloroacetyl group provides a highly reactive site for efficient nucleophilic substitution and peptide-like bonding.
- Consistent Quality: Produced under rigorous quality control standards to minimize impurities that could interfere with downstream catalytic processes.
- Standardized Physical Form: Supplied as a stable crystalline powder, facilitating accurate weighing and handling in large-scale production.
- Reliable Storage Stability: Formulated to remain stable under recommended cool and dry conditions for extended shelf life.
