3-Fluoro-2'-(trifluoromethyl)-[1,1'-biphenyl]-4-carboxylic acid CAS 505083-00-1

Description

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.

CATO supplies 3-Fluoro-2'-(trifluoromethyl)-[1,1'-biphenyl]-4-carboxylic acid (CAS 505083-00-1), a certified reference material (molecular formula C14H8F4O2, MW 284.21 g/mol) for analytical method development and quality control.

3-Fluoro-2'-(trifluoromethyl)-[1,1'-biphenyl]-4-carboxylic acid (C14H8F4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. 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 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.
