Quality Control

Our 5,5,8,8-Tetramethyl-5,6,7,8-Tetrahydro-2-Naphthalenyl Isocyanate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every 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, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and water.
