Methyl 5-bromo-4-hydroxy-[1,1'-biphenyl]-3-carboxylate (CAS 1155261-80-5) is a high-purity analytical reference standard with the molecular formula C14H11BrO3 and a molecular weight of 307.14 g/mol.
Methyl 5-bromo-4-hydroxy-[1,1'-biphenyl]-3-carboxylate (C14H11BrO3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
