2,4,6-Trichlorobiphenyl-2′,3′,4′,5′,6′-d5 (CAS 1219794-85-0) is a high-purity analytical reference standard with the molecular formula C12H2D5Cl3 and a molecular weight of 262.57 g/mol.
Owing to deuterium isotope labeling, chlorine substitution, an aromatic ring system, 2,4,6-Trichlorobiphenyl-2′,3′,4′,5′,6′-d5 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 262.57 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2,4,6-Trichlorobiphenyl-2′,3′,4′,5′,6′-d5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
