Quality Control

Our 2-Chloro-5-(4-Chlorophenoxy)-4-(Dimethylamino)Benzenediazonium Hydrogen Sulphate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for sensitive synthetic applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and moisture content. Our quality system is designed to meet the stringent requirements of GMP and ISO 9001 standards where applicable.

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 material must be handled under an inert atmosphere (e.g., nitrogen or argon) in a moisture-controlled environment to prevent decomposition and oxidation. Keep away from heat, sparks, and open flame.
