Quality Control

Our production of 1,2-Benzisoselenazol-3(2H)-One, 5-Nitro-2-Phenyl- adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and development purposes. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the original container. Keep away from heat and incompatible materials.
