Product overview
(S)-(+)-2-Chlorophenylglycine methyl ester (L)-(+)-tartrate is a chiral amino acid ester salt formed with (L)-(+)-tartaric acid. It is a white to off-white crystalline powder with excellent optical purity, and serves as a key chiral building block for the asymmetric synthesis of pharmaceutical actives, especially in the preparation of the chiral side chain of clopidogrel intermediates. in water. In acidic solutions, it is colorless, while in basic solutions, it turns pink to purple.
Key features
- High optical purity (S)-configuration ensuring reliable chirality transfer
- Stable tartaric acid salt form, easy to store and handle
- White crystalline powder with low impurity profile (≥99%)
- Excellent solubility profile suitable for salt resolution processes
- Standard packaging (25Kg/Drum) suitable for industrial use
Applications
- Key chiral intermediate for the synthesis of clopidogrel intermediates
- Building block for chiral 2-chlorophenylglycine derivatives in API synthesis
- Raw material for asymmetric synthesis in pharmaceutical R&D and production
- Used in resolution and optical purification of racemic phenylglycine esters
- Applied in fine chemical synthesis requiring chiral amino acid ester units
