Description

Azlocillin is a semisynthetic, broad-spectrum penicillin antibiotic belonging to the acylureidopenicillin class. Its primary value lies in its potent activity against a wide range of Gram-negative bacteria, including many strains of *Pseudomonas aeruginosa*, making it a critical agent in specific therapeutic areas. This compound is essential for pharmaceutical manufacturers and research institutions developing or producing injectable antibiotic formulations. Azlocillin CAS NO 37091-66-0 represents a key intermediate and active pharmaceutical ingredient for advanced anti-infective applications.

Application

• Active Pharmaceutical Ingredient (API) in the manufacture of injectable antibiotic formulations.
• Research & Development of new antibacterial agents and combination therapies.
• Reference Standard for quality control and analytical testing in pharmaceutical laboratories.
• Veterinary Medicine for the development of treatments for bacterial infections in animals.
• Microbiological Studies for investigating bacterial resistance mechanisms and efficacy profiles.
