Quality Control

Every batch of 4-Amino-5-Chloro-1,2,3-Benzothiadiazole is manufactured and tested under a strict quality management system. We provide comprehensive analytical documentation to ensure traceability and compliance with your project requirements. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee batch-to-batch consistency and support your regulatory needs.

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 opening to prevent degradation from atmospheric moisture.
