Description

Spiramycin Base CAS NO 679439-18-0 is a macrolide antibiotic belonging to the spiramycin family, serving as the fundamental active pharmaceutical ingredient (API) for various formulations. It is valued for its broad-spectrum activity against Gram-positive bacteria and certain mycoplasmas, making it a critical component in veterinary and pharmaceutical manufacturing. This compound is essential for producers of animal health products, feed additives, and researchers developing antimicrobial therapies.

Application

• Primary raw material for the synthesis of finished veterinary pharmaceutical formulations, including injectables and premixes.
• Active ingredient in medicated animal feed for the prevention and treatment of respiratory and enteric infections in livestock and poultry.
• Key intermediate in the production of human pharmaceutical-grade spiramycin for specific therapeutic applications.
• Reference standard in quality control and analytical laboratories for method development and validation.
• Used in research and development of new antibiotic combinations and delivery systems.
• Component in the manufacture of aquaculture treatments for bacterial diseases in farmed fish.
