Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5'-Dibromo-[1,1'-biphenyl]-2,2'-dicarboxylic acid.
5,5'-Dibromo-[1,1'-biphenyl]-2,2'-dicarboxylic acid (CAS 13974-99-7) is a high-purity analytical reference standard with the molecular formula C14H8Br2O4 and a molecular weight of 400.02 g/mol.
Based on its molecular formula C14H8Br2O4, 5,5'-Dibromo-[1,1'-biphenyl]-2,2'-dicarboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 400.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 5,5'-Dibromo-[1,1'-biphenyl]-2,2'-dicarboxylic acid 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.
