Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 248.61 g/mol gives 5-Methyl-2-(trifluoromethyl)furan-3-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Methyl-2-(trifluoromethyl)furan-3-sulfonyl chloride (CAS 306935-02-4), a certified reference material (molecular formula C6H4ClF3O3S, MW 248.61 g/mol) for analytical method development and quality control.
Structurally, 5-Methyl-2-(trifluoromethyl)furan-3-sulfonyl chloride (C6H4ClF3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 248.61 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
