Quality Control

Our production of 3-(o-Isocyanatobenzyl)-p-Tolyl Isocyanate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, purity profiling, and impurity identification, to ensure consistency and reliability. Certificates of Analysis (COA) documenting all critical parameters are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation. Isocyanate-specific safety and handling procedures must be followed.
