Quality Control

Our 1,3-Diisocyano-2,2-Dimethyl-Propane is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided to support your quality assurance and regulatory needs.

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 highly volatile and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation and polymerization.
