Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 151.03 g/mol gives 1,4-Dichlorobenzene-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,4-Dichlorobenzene-d4 (CAS 3855-82-1), molecular formula C6D4Cl2 and molecular weight 151.03 g/mol, is a CATO reference standard with documented purity and traceability.
1,4-Dichlorobenzene-d4 (C6D4Cl2) contains deuterium isotope labeling, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 1,4-Dichlorobenzene-d4 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.
