Quality Control

Our 2,6-Dimethylphenyl Isocyanate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and impurity profiling, to ensure it meets high-purity standards suitable for industrial and research applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture.
