Description

Sulfathiazole CAS NO 72-14-0 is a sulfonamide antibiotic belonging to the class of synthetic antimicrobial agents. It is a critical intermediate and active pharmaceutical ingredient (API) valued for its bacteriostatic properties against a broad spectrum of gram-positive and gram-negative organisms. This compound is essential for manufacturers in the pharmaceutical industry, particularly for the formulation of veterinary medicines and, historically, in human antibacterial treatments.

Application

• Pharmaceutical API: Primary use as an active ingredient in antibacterial formulations.
• Veterinary Medicine: Key component in topical and systemic treatments for bacterial infections in livestock and companion animals.
• Intermediate Synthesis: Serves as a crucial building block for synthesizing more complex sulfonamide derivatives.
• Research & Development: Used in microbiological studies and as a reference standard in analytical laboratories.
• Aquaculture: Employed in the treatment of bacterial diseases in fish farming operations.
