Quality Control

Our production of 1,2,5-Oxadiazole-3-Carboxamide, 4-Amino-, 5-Oxide (9Ci) adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, NMR, and mass spectrometry for identity confirmation and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and related substances is provided with every 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 after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
