Chemical Structure
Description
5-Bromo-1-benzothiophene-3-sulfonyl chloride (CAS 30214-08-5), molecular formula C8H4BrClO2S2 and molecular weight 311.60 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H4BrClO2S2, 5-Bromo-1-benzothiophene-3-sulfonyl chloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.60 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.
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.
