Chemical Structure
Description
CATO supplies 4-((4-Chlorophenyl)thio)butane-1-sulfonyl chloride (CAS 165590-45-4), a certified reference material (molecular formula C10H12Cl2O2S2, MW 299.24 g/mol) for analytical method development and quality control.
Structurally, 4-((4-Chlorophenyl)thio)butane-1-sulfonyl chloride (C10H12Cl2O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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 299.24 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
