2-Chloro-4-(methylsulfonyl)-3-((2,2,2-trifluoroethoxy)methyl)benzoic acid CAS 120100-77-8

Description

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.

2-Chloro-4-(methylsulfonyl)-3-((2,2,2-trifluoroethoxy)methyl)benzoic acid (CAS 120100-77-8) is a high-purity analytical reference standard with the molecular formula C11H10ClF3O5S and a molecular weight of 346.71 g/mol.

Based on its molecular formula C11H10ClF3O5S, 2-Chloro-4-(methylsulfonyl)-3-((2,2,2-trifluoroethoxy)methyl)benzoic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 346.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
