Quality Control

Our 2,5-Di-tert-Butylphenyl Isocyanate is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including HPLC, GC, and NMR spectroscopy. 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 place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, open flames, and strong bases.
