Quality Control

Our Sulfathiazole Sodium is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, related substances, and residual solvents, supporting compliance with cGMP and relevant pharmacopeial guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Recommended long-term storage temperature is 2-8°C.
