2-(4-Chlorophenyl)-3-(difluoromethyl)benzofuran CAS 821769-99-7

Description

Structurally, 2-(4-Chlorophenyl)-3-(difluoromethyl)benzofuran (C15H9ClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 278.68 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-(4-Chlorophenyl)-3-(difluoromethyl)benzofuran (CAS 821769-99-7), molecular formula C15H9ClF2O and molecular weight 278.68 g/mol, is a CATO reference standard with documented purity and traceability.

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.
