Quality Control

Our 2,1-Benzisoxazole-4,5-Dione,4-Oxime,(4Z)-(9Ci) is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all 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 a controlled room temperature (15-25°C). Due to its sensitivity to light and tendency for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
