Description

Rifamycin Verde CAS NO 72428-95-6 is a semi-synthetic derivative of the rifamycin antibiotic class, characterized by its distinct green color. This compound is valued for its potent antibacterial activity, particularly against Gram-positive bacteria and mycobacteria. It serves as a critical intermediate and active pharmaceutical ingredient (API) for manufacturers in the pharmaceutical and veterinary medicine industries, where it is used in the development of specialized anti-infective treatments.

Application

• Pharmaceutical API: Primary use as an active pharmaceutical ingredient in the formulation of anti-tuberculosis and other antibacterial medications.
• Veterinary Medicine: Key component in topical and systemic treatments for bacterial infections in livestock and companion animals.
• Research & Development: Essential reference standard and building block in microbiological research and the development of new antibiotic analogs.
• Specialized Formulations: Used in the production of medicated creams, ointments, and wound dressings for targeted antibacterial action.
• Biochemical Studies: Employed as a tool to study bacterial RNA polymerase inhibition and mechanisms of antibiotic resistance.
