5-(2-Chlorophenyl)-2-(trifluoromethyl)furan-3-carboxylic acid CAS 243977-26-6

Description

Compared with other compounds in its class, the molecular weight of 290.62 g/mol gives 5-(2-Chlorophenyl)-2-(trifluoromethyl)furan-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(2-Chlorophenyl)-2-(trifluoromethyl)furan-3-carboxylic acid (CAS 243977-26-6), molecular formula C12H6ClF3O3 and molecular weight 290.62 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 5-(2-Chlorophenyl)-2-(trifluoromethyl)furan-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
