Chemical Structure
Description
2-((2,5-Dichlorophenyl)sulfonyl)ethan-1-ol (CAS 107737-91-7) is a high-purity analytical reference standard with the molecular formula C8H8Cl2O3S and a molecular weight of 255.12 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-((2,5-Dichlorophenyl)sulfonyl)ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
