Oxacillin Sodium, identified by the CAS number 1173-88-2, is a semi-synthetic penicillin antibiotic widely recognized for its stability against staphylococcal beta-lactamases. With a molecular formula of C₁₉H₁₇N₂NaO₅S and a molecular weight of approximately 404.4 g/mol, this sodium salt serves as a critical therapeutic agent in modern medicine. It is specifically designed to treat infections caused by penicillinase-producing strains of Staphylococcus aureus, including those resistant to standard penicillin G. The "99% up" purity specification indicates that this product meets high-grade pharmaceutical standards, ensuring minimal impurities and maximum efficacy for clinical applications.
The primary mechanism of action involves inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby preventing the cross-linking of peptidoglycan layers essential for bacterial structural integrity. This leads to cell lysis and death. Oxacillin Sodium is predominantly administered via intravenous or intramuscular routes due to its poor oral bioavailability. Its clinical utility extends beyond simple skin and soft tissue infections; it is also employed in treating serious conditions such as bacteremia, osteomyelitis, pneumonia, and endocarditis caused by susceptible organisms. In industrial contexts, high-purity Oxacillin Sodium is frequently utilized as a reference standard in quality control laboratories for antibiotic potency testing and method validation.
Manufacturers adhere to Good Manufacturing Practice (GMP) guidelines to ensure consistent quality, safety, and sterility throughout the production process. The availability of this compound with a Declaration of Manufacture (DMF) on file simplifies regulatory submissions for pharmaceutical companies developing formulations containing this active ingredient. While generally well-tolerated, patients with a history of hypersensitivity to penicillins must avoid its use to prevent severe allergic reactions. As a cornerstone in combating methicillin-resistant strains before the emergence of MRSA became dominant, Oxacillin Sodium remains a vital component of antimicrobial stewardship programs globally. Its continued relevance underscores the importance of maintaining high-quality supply chains for essential antibiotics in both human and veterinary medicine sectors.
