Quality Control

Our 2-sec-Butylphenyl Isocyanate 97 is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including chromatography and spectroscopic methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture.
