Description

Ribostamycin Sulfate CAS NO 53797-35-6 is the sulfate salt form of ribostamycin, a broad-spectrum aminoglycoside antibiotic derived from *Streptomyces ribosidificus*. This compound is valued for its potent antibacterial activity, particularly against Gram-negative bacteria, making it a critical intermediate and active pharmaceutical ingredient (API). It is primarily utilized by pharmaceutical manufacturers and research institutions involved in developing and producing antibiotic formulations, veterinary medicines, and microbiological research reagents.

Application

• Pharmaceutical API: Serves as a key active ingredient in the formulation of injectable antibiotic drugs.
• Veterinary Medicine: Used in the development of treatments for bacterial infections in livestock and companion animals.
• Biochemical Research: Employed as a selective agent in microbiology and molecular biology to study bacterial protein synthesis and resistance mechanisms.
• Reference Standard: Functions as a high-purity analytical standard for quality control and regulatory testing in pharmaceutical laboratories.
• Intermediate Synthesis: Acts as a crucial starting material or intermediate for the chemical synthesis of more complex aminoglycoside derivatives.
