Description

Pristinamycin Ia CAS NO 3131-03-1 is a key component of the pristinamycin complex, a streptogramin antibiotic produced by *Streptomyces pristinaespiralis*. This compound is valued for its potent antibacterial activity, particularly against Gram-positive pathogens, and serves as a critical intermediate in pharmaceutical research and development. It is essential for scientists and manufacturers in the pharmaceutical and biotechnology sectors focused on antibiotic development, microbiological studies, and the synthesis of novel therapeutic agents.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of advanced antibiotic formulations and combination therapies.
• Antimicrobial Research: Used as a reference standard and active agent in microbiological assays to study bacterial resistance mechanisms and efficacy.
• Veterinary Medicine: Employed in the development of treatments for bacterial infections in animals.
• Biochemical Studies: Utilized in research to investigate the mode of action of streptogramin antibiotics at the molecular level.
• API Development: Acts as a starting material or intermediate in the production of Active Pharmaceutical Ingredients (APIs) for human and veterinary use.
