Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-((1-Chloro-2,2,2-trifluoroethyl)thio)acetic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-((1-Chloro-2,2,2-trifluoroethyl)thio)acetic acid (CAS 885461-01-8) is a high-purity analytical reference standard with the molecular formula C4H4ClF3O2S and a molecular weight of 208.59 g/mol.
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.
