Chemical Structure
Description
CATO supplies 2,2'-Dibromo-[1,1'-biphenyl]-4,4'-diol (CAS 84530-62-1), a certified reference material (molecular formula C12H8Br2O2, MW 344.00 g/mol) for analytical method development and quality control.
2,2'-Dibromo-[1,1'-biphenyl]-4,4'-diol (C12H8Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2,2'-Dibromo-[1,1'-biphenyl]-4,4'-diol 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.
