Cefazolin Related Compound D, also known as Cefazolin open-ring lactone, is a critical degradation impurity of the first-generation cephalosporin antibiotic. It arises from the hydrolysis of the beta-lactam ring under acidic or thermal stress conditions. The molecular formula is C14H16N2O5S, with CAS No. 108057-99-6.
Strictly store at -20°C in desiccated conditions to prevent further degradation. Handle using appropriate PPE due to potential allergenicity associated with beta-lactam structures. Not intended for clinical administration; strictly for laboratory analysis only.
