Quality Control

Our 4-[Ethyl(2-Hydroxyethyl)Amino]Benzenediazonium Chloride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC and NMR to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters 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 (15-25°C). Due to its hygroscopic and light-sensitive nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent moisture absorption and decomposition. Keep away from heat, sparks, and incompatible materials.
