89520-72-9 Benzene, 1-[(chloromethyl)sulfonyl]-4-(trifluoromethyl)- DTXSID00459514 CAS 89520-72-9

Description

CATO supplies 89520-72-9 Benzene, 1-[(chloromethyl)sulfonyl]-4-(trifluoromethyl)- DTXSID00459514 (CAS 89520-72-9), a certified reference material (molecular formula C8H6ClF3O2S, MW 258.65 g/mol) for analytical method development and quality control.

89520-72-9 Benzene, 1-[(chloromethyl)sulfonyl]-4-(trifluoromethyl)- DTXSID00459514 (C8H6ClF3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
