Quality Control

Our Trisulfapyrimidine is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency, meeting the requirements for use as a pharmaceutical intermediate and reference material. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, related substances, and residual solvents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
