Cefoperazone EP Impurity B is a critical degradation product and synthetic intermediate of the cephalosporin antibiotic Cefoperazone. It serves as a reference standard for pharmaceutical quality control to ensure compliance with European Pharmacopoeia (EP) specifications regarding purity profiles. The compound is characterized by the molecular formula C19H18N6O5S2 and CAS No. 64720-66-1. Its synthesis typically involves specific oxidation or hydrolysis steps within the cephem nucleus manufacturing process.
This substance is intended solely for laboratory research and analytical validation, not for clinical administration. Storage requires keeping the material in a cool, dry environment below 25°C, protected from light and moisture to prevent structural decomposition. Personnel must utilize appropriate PPE when handling due to potential sensitization risks associated with beta-lactam compounds.
