Quality Control

Our 2,5-Dimethylphenyl Isocyanate is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including assay by GC/HPLC and impurity profile analysis, to ensure it meets the high-purity standards required for industrial and research applications. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters are available upon request to support your quality assurance protocols.

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 tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture ingress.
