Cefpodoxime Proxetil EP Impurity B is a defined diastereomeric mixture serving as a critical reference standard for pharmaceutical quality control. Synthesized via specific chiral resolution or asymmetric coupling processes, it ensures the purity of the active pharmaceutical ingredient (API). Molecular Formula: C19H20N6O8S2; CAS No.: 145724-39-2.
Store strictly under inert atmosphere at -20°C to prevent diastereomer interconversion. Handle with appropriate PPE in a fume hood; avoid direct skin contact due to potential sensitization risks associated with cephalosporin derivatives.
