Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-hydroxy-6-iodobenzo[b]thiophene-2-carboxylate.
CATO supplies Ethyl 3-hydroxy-6-iodobenzo[b]thiophene-2-carboxylate (CAS 2167372-67-8), a certified reference material (molecular formula C11H9IO3S, MW 348.16 g/mol) for analytical method development and quality control.
Ethyl 3-hydroxy-6-iodobenzo[b]thiophene-2-carboxylate (C11H9IO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 Ethyl 3-hydroxy-6-iodobenzo[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.
