Quality Control

Our 3-Isoxazolecarbamic Acid, Ethyl Ester (5Ci) is manufactured under strict quality control protocols to ensure high chemical purity and isotopic enrichment. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as chemical purity (by HPLC), isotopic purity, and identity confirmation. We adhere to cGMP principles where applicable to support our clients' regulatory and research 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 after opening to prevent degradation.
