Quality Control

Our 3-(3-Isocyanatophenyl)-5-Methyl-1,2,4-Oxadiazole is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flames.
