Quality Control

Our p-Tolyl Isocyanate is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including GC and HPLC, to monitor key parameters such as assay and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with each shipment to support your quality assurance and regulatory compliance needs.

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). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent degradation and polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
