Quality Control

Our 3-Chloro-4-(Hydroxyimino)-2,5-Cyclohexadien-1-One is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet rigorous research and industrial grade specifications. A detailed Certificate of Analysis (COA) documenting identity, purity, and related substances is provided with every shipment to support your quality assurance protocols.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames.
