Description

Sodium Sulfadiazine CAS NO 547-32-0 is the sodium salt form of sulfadiazine, a key sulfonamide antibiotic. This compound is valued for its high purity and consistent quality, which are critical for reliable formulation and therapeutic efficacy. It is primarily required by pharmaceutical manufacturers for the production of injectable and topical antibacterial medications, serving essential roles in both human and veterinary medicine.

Application

• Pharmaceutical Active Ingredient (API): Core component in the formulation of antibacterial injections and infusions for systemic infections.
• Topical Preparations: Used in creams, ointments, and wound dressings for the treatment of burns and skin infections to prevent bacterial colonization.
• Veterinary Medicine: Employed in antibacterial treatments for livestock, poultry, and companion animals.
• Combination Therapy: Often used in conjunction with other agents, such as silver, in specialized burn creams for enhanced antimicrobial action.
• Research & Development: Serves as a reference standard and starting material in pharmaceutical R&D for new antibacterial formulations.
