Quality Control

Our 2-Chloroaniline-5-Sulfonicacid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and titration methods, to ensure it meets precise purity and compositional specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your technical requirements.

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 sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
