5-(2,3,4,5,6-Pentafluorophenyl)-2-thiophene carboxylic acid CAS 893737-99-0

Description

CATO supplies 5-(2,3,4,5,6-Pentafluorophenyl)-2-thiophene carboxylic acid (CAS 893737-99-0), a certified reference material (molecular formula C11H3F5O2S, MW 294.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H3F5O2S, 5-(2,3,4,5,6-Pentafluorophenyl)-2-thiophene carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 294.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
