2,3',4',5-Tetrachlorobiphenyl-3,4,6-d3 (CAS 1219794-77-0), molecular formula C12H3D3Cl4 and molecular weight 295.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, chlorine substitution, an aromatic ring system, 2,3',4',5-Tetrachlorobiphenyl-3,4,6-d3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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), 2,3',4',5-Tetrachlorobiphenyl-3,4,6-d3 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.
