2-(4-Chlorobenzoyl)-3-({[3-(trifluoromethyl)phenyl]sulfanyl}methyl)-1-benzofuran CAS 338411-49-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Chlorobenzoyl)-3-({[3-(trifluoromethyl)phenyl]sulfanyl}methyl)-1-benzofuran.

2-(4-Chlorobenzoyl)-3-({[3-(trifluoromethyl)phenyl]sulfanyl}methyl)-1-benzofuran (CAS 338411-49-7), molecular formula C23H14ClF3O2S and molecular weight 446.87 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-(4-Chlorobenzoyl)-3-({[3-(trifluoromethyl)phenyl]sulfanyl}methyl)-1-benzofuran is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 446.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
