Quality Control

Every batch of 2,6-Bis(1-Methylethyl)Phenoxysulfonylisocyanate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the precise requirements of advanced synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container 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 strong bases.
