Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 400.02 g/mol gives 4,4'-Dibromo-[1,1'-biphenyl]-2,2'-dicarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,4'-Dibromo-[1,1'-biphenyl]-2,2'-dicarboxylic acid (CAS 54389-67-2), a certified reference material (molecular formula C14H8Br2O4, MW 400.02 g/mol) for analytical method development and quality control.
4,4'-Dibromo-[1,1'-biphenyl]-2,2'-dicarboxylic acid (C14H8Br2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
