5-Chloro-2',5'-difluoro-[1,1'-biphenyl]-3-ol CAS 1261990-27-5

Description

Compared with other compounds in its class, the molecular weight of 240.63 g/mol gives 5-Chloro-2',5'-difluoro-[1,1'-biphenyl]-3-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Chloro-2',5'-difluoro-[1,1'-biphenyl]-3-ol (CAS 1261990-27-5), a certified reference material (molecular formula C12H7ClF2O, MW 240.63 g/mol) for analytical method development and quality control.

5-Chloro-2',5'-difluoro-[1,1'-biphenyl]-3-ol (C12H7ClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
