Cefradine Impurity D (Isomer 2) is a critical synthetic intermediate and reference standard in the pharmaceutical manufacturing of cephalosporin antibiotics. It serves as a specific diastereomeric impurity arising from stereochemical variations during the coupling process of the beta-lactam ring formation. The compound features the molecular formula C16H17N3O4S and is identified by CAS No. 109856-58-2.
Store under inert atmosphere at -20°C protected from light and moisture. Handle with appropriate PPE to avoid skin contact or inhalation, as high-purity crystalline powders may pose respiratory sensitization risks. Strictly limit use to laboratory settings; not intended for direct clinical administration.
