Description
CATO manufactures Ethyl 4-chlorobenzo[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.
Ethyl 4-chlorobenzo[b]thiophene-2-carboxylate (CAS 1207537-67-4), molecular formula C11H9ClO2S and molecular weight 240.71 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 4-chlorobenzo[b]thiophene-2-carboxylate (C11H9ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
