Chemical Structure
Description
Structurally, 2-(2-Bromophenoxy)ethane-1-sulfonyl chloride (C8H8BrClO3S) 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 299.57 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).
2-(2-Bromophenoxy)ethane-1-sulfonyl chloride (CAS 1018289-19-4) is a high-purity analytical reference standard with the molecular formula C8H8BrClO3S and a molecular weight of 299.57 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
