1,1'-([1,1'-biphenyl]-4,4'-diyl)bis(2-chloroethan-1-one) CAS 24860-53-5

Description

CATO manufactures 1,1'-([1,1'-biphenyl]-4,4'-diyl)bis(2-chloroethan-1-one) 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.

1,1'-([1,1'-biphenyl]-4,4'-diyl)bis(2-chloroethan-1-one) (CAS 24860-53-5), molecular formula C16H12Cl2O2 and molecular weight 307.17 g/mol, is a CATO reference standard with documented purity and traceability.

1,1'-([1,1'-biphenyl]-4,4'-diyl)bis(2-chloroethan-1-one) (C16H12Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
