Quality Control

Our production of 3-(4-Chlorophenyl)-3-Oxopropanal o-Methyloxime adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR to confirm identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
