Overview
(+)-Clopidogrel (-)-camphorsulfonic acid is a diastereomeric salt used as an intermediate in the pharmaceutical synthesis of clopidogrel. The core process involves resolving racemic clopidogrel with chiral camphorsulfonic acid to isolate the active enantiomer. Molecular formula: C21H28ClNO7S2; CAS No.: 159654-05-8.
Application
- API Manufacturing: Critical for producing high-purity clopidogrel base.
- Chiral Resolution: Used in large-scale asymmetric synthesis processes.
- Quality Control: Serves as a reference standard for enantiomeric purity testing.
Precautions
Store in a cool, dry place under inert atmosphere. Avoid contact with skin and eyes; wear appropriate PPE. Not for direct clinical use; strictly for industrial pharmaceutical processing only.
