Chemical Structure
Description
Structurally, 3,5-Dibromobenzene-1-sulfonyl chloride (C6H3Br2ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 334.41 g/mol, it falls into the moderately-high-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).
3,5-Dibromobenzene-1-sulfonyl chloride (CAS 39213-20-2) is a high-purity analytical reference standard with the molecular formula C6H3Br2ClO2S and a molecular weight of 334.41 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.
