2',5'-Dichloro-[1,1'-biphenyl]-2,5-dione CAS 79756-69-7

Description

Compared with other compounds in its class, the molecular weight of 253.08 g/mol gives 2',5'-Dichloro-[1,1'-biphenyl]-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2',5'-Dichloro-[1,1'-biphenyl]-2,5-dione (CAS 79756-69-7), a certified reference material (molecular formula C12H6Cl2O2, MW 253.08 g/mol) for analytical method development and quality control.

The molecular framework of 2',5'-Dichloro-[1,1'-biphenyl]-2,5-dione (C12H6Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 2',5'-Dichloro-[1,1'-biphenyl]-2,5-dione 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.
