Quality Control

Every batch of 4-Nitrosoquinoline 1-Oxide is manufactured and tested under a rigorous quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
