Description

Kitasamycin Tartrate CAS NO 37280-56-1 is a tartrate salt form of the macrolide antibiotic kitasamycin, offering enhanced stability and solubility for pharmaceutical formulations. This compound is critical for its potent antibacterial activity against a range of Gram-positive bacteria and mycoplasmas. It is primarily required by manufacturers in the veterinary and pharmaceutical industries for the production of therapeutic agents.

Application

• Veterinary Medicine: Key active ingredient in injectable solutions, premixes, and feed additives for the treatment and prevention of respiratory and enteric infections in livestock and poultry.
• Pharmaceutical Intermediates: Serves as a crucial starting material or intermediate in the synthesis of more complex macrolide antibiotic derivatives.
• Aquaculture: Used in medicated feeds to control bacterial diseases in farmed fish and shrimp.
• Research & Development: Employed in microbiological research, antimicrobial susceptibility testing, and as a standard in analytical laboratories.
• Veterinary Premixes: Incorporated into powder or granular premixes for uniform distribution in animal feed to promote herd health.
