Description
CATO manufactures 6-bromo-3,4-dihydro-1H-2-benzothiopyran-4-one 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.
CATO supplies 6-bromo-3,4-dihydro-1H-2-benzothiopyran-4-one (CAS 880553-98-0), a certified reference material (molecular formula C9H7BrOS, MW 243.12 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 6-bromo-3,4-dihydro-1H-2-benzothiopyran-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.12 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.
