Description

Virginiamycin M1 is a specific component of the Virginiamycin antibiotic complex, a streptogramin primarily used as a veterinary feed additive. Its precise activity is critical for promoting growth and preventing certain bacterial infections in livestock. This high-purity compound is essential for manufacturers of animal health products, feed premixes, and for research into antibiotic mechanisms and resistance.

Application

• Veterinary Feed Additive: Key active component in growth-promoting feed supplements for poultry, swine, and cattle.
• Animal Health Formulations: Used in the manufacture of medicated feeds and premixes to prevent and control specific bacterial enteritis.
• Pharmaceutical Intermediate: Serves as a critical starting material or reference standard in the production of veterinary antibiotic preparations.
• Microbiological Research: Used as a reference compound in studies of streptogramin antibiotics, protein synthesis inhibition, and bacterial resistance mechanisms.
• Quality Control Standard: Employed as an analytical reference standard in HPLC and microbiological assays for product quality assurance.
