Quality Control

Our production of this specialized isocyanate adheres to strict quality protocols to ensure batch-to-batch consistency and reliable performance in downstream synthesis. Quality is verified through analytical techniques including HPLC, FT-IR, and titration to confirm isocyanate content and purity. A Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 maximize stability and minimize viscosity increase. This product is hygroscopic (moisture-sensitive). Containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent reaction with atmospheric moisture and carbon dioxide.
