Quality Control

Our Phenyl 2,4-Diisocyanato-5-Methylbenzenesulphonate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, purity profiling, and impurity identification, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency.

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 under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture ingress. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
