Quality Control

Our production of 6-Chloro-3-Nitrotrotoluene-2-Sulphonic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and meet the exacting requirements of our global clientele. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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 strong bases and oxidizing agents.
