Description

Oxacillin Sodium CAS NO 1773-88-2 is a semi-synthetic penicillinase-resistant β-lactam antibiotic. It is a critical active pharmaceutical ingredient (API) valued for its efficacy against penicillin-resistant staphylococcal infections. This product is essential for pharmaceutical manufacturers producing injectable and oral antibiotic formulations. We supply high-purity Oxacillin Sodium to meet the stringent demands of the global pharmaceutical industry.

Application

• Pharmaceutical API: Primary use as the active ingredient in injectable antibiotic formulations.
• Oral Dosage Forms: Used in the manufacture of capsules and oral suspensions for systemic antibiotic therapy.
• Veterinary Medicine: Formulated for treating bacterial infections in animals.
• Research & Development: Serves as a reference standard and key intermediate in antimicrobial research and new drug development.
• Hospital Compounding: Utilized in pharmacy compounding for specific patient needs where commercial formulations are unsuitable.
