Quality Control

Our 5-(p-Isocyanatobenzyl)-o-Tolyl Isocyanate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by HPLC and impurity profiling, to ensure high purity and batch-to-batch consistency suitable for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation and polymerization. Due to its highly volatile and moisture-sensitive nature, containers must be kept sealed and allowed to reach room temperature before opening to prevent moisture ingress. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
