Quality Control

Our 3-Chlorobenzene-1,2-Dicarbonitrile is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, GC, and NMR, to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from heat, sparks, and open flame.
