Chemical Structure
Description
The occurrence of 2,4′-Dichlorobiphenyl-d8 is closely related to deuterium isotope labeling, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,4′-Dichlorobiphenyl-d8 (CAS 1219795-19-3), a certified reference material (molecular formula C12D8Cl2, MW 231.15 g/mol) for analytical method development and quality control.
Based on its molecular formula C12D8Cl2, 2,4′-Dichlorobiphenyl-d8 contains deuterium isotope labeling, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 231.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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′-Dichlorobiphenyl-d8 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.
