Description

Sulfisozole Sodium is a sodium salt derivative of the sulfonamide antibiotic sulfisoxazole, identified by CAS NO 79921-43-0. This compound is valued for its enhanced solubility and stability profile compared to its parent molecule, making it a critical intermediate in pharmaceutical synthesis. It is primarily required by manufacturers in the pharmaceutical and fine chemical industries for the development of antibacterial formulations and advanced research applications.

Application

• Pharmaceutical Intermediate: Key starting material or active pharmaceutical ingredient (API) in the synthesis of antibacterial medications.
• Veterinary Medicine: Used in formulating antibacterial treatments for livestock and companion animals.
• Research & Development: Serves as a standard or reagent in microbiological and pharmacological studies targeting gram-positive and gram-negative bacteria.
• Fine Chemical Synthesis: Employed as a building block for creating more complex sulfonamide-derived compounds with specialized properties.

Quality Control

Our Sulfisozole Sodium is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets high-grade standards suitable for pharmaceutical applications. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
