Description

Compared with other compounds in its class, the molecular weight of 323.51 g/mol gives 5-Bromo-2-(trifluoromethyl)benzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-2-(trifluoromethyl)benzenesulfonyl chloride (CAS 1375065-87-4) is a high-purity analytical reference standard with the molecular formula C7H3BrClF3O2S and a molecular weight of 323.51 g/mol.

Structurally, 5-Bromo-2-(trifluoromethyl)benzenesulfonyl chloride (C7H3BrClF3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 323.51 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
