Description

Ceftazidime CAS NO 78439-06-2 is a potent third-generation cephalosporin antibiotic belonging to the β-lactam class. It is valued for its broad-spectrum bactericidal activity, particularly against difficult-to-treat Gram-negative bacteria, including *Pseudomonas aeruginosa*. This product is essential for pharmaceutical manufacturers and research institutions developing injectable antibiotic formulations for serious systemic infections.

Application

• Pharmaceutical Active Ingredient (API): Primary use in the manufacture of sterile injectable antibiotic drugs.
• Hospital & Critical Care Formulations: For treating severe infections like pneumonia, septicemia, and meningitis, especially in immunocompromised patients.
• Anti-Pseudomonal Therapy: A key agent in combating infections caused by multidrug-resistant *Pseudomonas aeruginosa*.
• Combination Drug Development: Used in research for fixed-dose combination therapies with other antibiotics like avibactam.
• Veterinary Medicine: Formulated for treating serious bacterial infections in animals.
• Reference Standard: Serves as a high-purity analytical standard for quality control testing in laboratories.
