Quality Control

Our Co-Trimazine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent purity and identity criteria, suitable for pharmaceutical intermediate applications. Certificates of Analysis (COA) detailing purity, related substances, and other critical parameters are provided with every shipment to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
