Quality Control

Every batch of 3,5-Dichlorobenzidine is subjected to stringent analytical testing to ensure it meets exacting purity and consistency standards required for industrial synthesis. Our quality assurance protocol includes identity confirmation by spectroscopic methods and precise quantification of assay and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and specific impurity limits is provided with each shipment to guarantee traceability and compliance with your internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its light-sensitive and easily oxidized nature, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality. Recommended storage temperature is 2-8°C for extended stability.
