Quality Control

Our 5-Amino-2-Chloro-4-Hydroxy-Benzoic Acid is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure it meets the high standards required for pharmaceutical and fine chemical applications. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming identity, purity, and impurity profiles. Our quality commitment ensures reliable supply chain integrity and batch-to-batch consistency for your critical processes.

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 opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
