Quality Control

Our 1-Isocyanato-3-Methoxypropane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay and impurity profile analysis by GC and/or HPLC, to ensure it meets high-purity standards suitable for synthesis and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
