What is (S)-Glycidyl Phthalimide?
(S)-2-(Oxiran-2-ylmethyl)Isoindoline-1,3-dione — (S)-Glycidyl Phthalimide — is a chiral epoxide-phthalimide building block listed as a USP reference substance. Its reactive (S)-configured epoxide ring undergoes nucleophilic ring-opening to build the chiral oxazolidinone core of Rivaroxaban with the correct stereochemistry. Prudence Lifecare also manufactures the other two major Rivaroxaban building blocks — 5-Chlorothiophene-2-Carboxylic Acid and 4-(4-Aminophenyl)Morpholin-3-One — alongside the finished Rivaroxaban API.
Application
- Rivaroxaban synthesis — chiral oxazolidinone building block
- Anticoagulant API manufacturing
- Custom synthesis & CDMO supply
- Pharmaceutical research & QC reference
