Capecitabine Impurity J refers to the α pair enantiomers, a critical chiral reference standard used in pharmaceutical quality control. Its molecular formula is C15H22FNO4 and CAS No. is 167930-85-6. This impurity arises during the synthesis of Capecitabine via asymmetric hydrogenation or resolution processes.
Store at -20°C under inert atmosphere to prevent racemization. Handle with appropriate PPE due to potential cytotoxicity. Strictly limit exposure in clinical settings to analytical quantities only.
