Description

Gentamicinc CAS NO 11097-82-8 is a potent aminoglycoside antibiotic complex, primarily composed of gentamicin C1, C1a, and C2. It is valued for its broad-spectrum bactericidal activity against a wide range of Gram-negative and some Gram-positive bacteria. This makes it a critical active pharmaceutical ingredient (API) for the formulation of injectable and topical medications. Key industrial users include pharmaceutical manufacturers, veterinary medicine producers, and research institutions focused on antimicrobial development.

Application

• Pharmaceutical API: Primary use in the manufacture of injectable antibiotic formulations for serious systemic infections.
• Veterinary Medicine: Used in topical ointments, eye/ear drops, and injectable solutions for treating bacterial infections in animals.
• Ophthalmic Preparations: Key ingredient in eye drops and ointments for treating bacterial conjunctivitis and corneal ulcers.
• Topical Creams & Ointments: Incorporated into dermatological products for skin and wound infections.
• Research & Development: Serves as a reference standard and active component in microbiological and pharmacological studies.
• Cell Culture: Used in selective media in biotechnology and cell culture laboratories to prevent bacterial contamination.
