Chemical Structure

tetrachloropyridin-4-amine CAS 2176-63-8 chemical structure

Description

tetrachloropyridin-4-amine (C5H2Cl4N2) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

tetrachloropyridin-4-amine (CAS 2176-63-8), molecular formula C5H2Cl4N2 and molecular weight 231.89 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), tetrachloropyridin-4-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
