Chemical Structure

(2-Chloroethanesulfinyl)benzene CAS 27998-60-3 chemical structure

Description

(2-Chloroethanesulfinyl)benzene (CAS 27998-60-3) is a high-purity analytical reference standard with the molecular formula C8H9ClOS and a molecular weight of 188.67 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, (2-Chloroethanesulfinyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.67 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.

CATO manufactures (2-Chloroethanesulfinyl)benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
