Quality Control

Our 2,6-Bis(o-Isocyanatobenzyl)Phenyl Isocyanate is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through analytical techniques including HPLC, titration, and IR spectroscopy. A Certificate of Analysis (COA) detailing purity, isocyanate content, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) to prevent reaction with atmospheric moisture and carbon dioxide, which can lead to polymerization or urea formation.
