Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl 3-(N-(3-chloro-4-methoxyphenyl)sulfamoyl)benzo[b]thiophene-2-carboxylate (CAS 932464-56-7), a certified reference material (molecular formula C18H16ClNO5S2, MW 425.91 g/mol) for analytical method development and quality control.
Ethyl 3-(N-(3-chloro-4-methoxyphenyl)sulfamoyl)benzo[b]thiophene-2-carboxylate (C18H16ClNO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Ethyl 3-(N-(3-chloro-4-methoxyphenyl)sulfamoyl)benzo[b]thiophene-2-carboxylate 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.
