Quality Control

Our production of 1,3,4-Thiadiazole,2-Ethyl-5-Isocyanato-(9Ci) adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR to confirm identity and quantify purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 flame.
