3-Bromo-4'-methyl-1,1'-biphenyl CAS 844856-52-6 chemical structure

Description

CATO supplies 3-Bromo-4'-methyl-1,1'-biphenyl (CAS 844856-52-6), a certified reference material (molecular formula C13H11Br, MW 247.13 g/mol) for analytical method development and quality control.

3-Bromo-4'-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.

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.
