Description
Compared with other compounds in its class, the molecular weight of 251.62 g/mol gives 7-Fluoro-2-oxo-2,3-dihydrobenzo[d]oxazole-6-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 7-Fluoro-2-oxo-2,3-dihydrobenzo[d]oxazole-6-sulfonyl chloride (CAS 2251113-44-5), a certified reference material (molecular formula C7H3ClFNO4S, MW 251.62 g/mol) for analytical method development and quality control.
7-Fluoro-2-oxo-2,3-dihydrobenzo[d]oxazole-6-sulfonyl chloride (C7H3ClFNO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 7-Fluoro-2-oxo-2,3-dihydrobenzo[d]oxazole-6-sulfonyl chloride 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.
