Quality Control

Our 1,1,1-Trihydroxyethyl Isocyanate is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with customer specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and quality assurance for your production processes.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent degradation.
