Description
As a certified reference material (CRM), 4-Bromo-3-methyl-1,1’-biphenyl 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.
4-Bromo-3-methyl-1,1’-biphenyl (CAS 92022-07-6) is a high-purity analytical reference standard with the molecular formula C13H11Br and a molecular weight of 247.13 g/mol.
4-Bromo-3-methyl-1,1’-biphenyl (C13H11Br) contains bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
