Cefoxitin EP Impurity E, also known as R-methoxy cefoxitin, is a critical chiral reference standard used in pharmaceutical quality control. It represents the R-enantiomer impurity arising during the synthesis of the cephamycin antibiotic Cefoxitin. The molecular formula is C16H17N3O8S (CAS: 59042-58-7). This compound is essential for validating stereoselectivity in manufacturing processes.
Store under inert atmosphere at -20°C to prevent hydrolysis and racemization. Handle only in certified laboratories using appropriate PPE due to potential sensitization risks. Not intended for direct clinical use; strictly for analytical purposes.
