Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-(5-bromobenzo[b]thiophen-3-yl)acetate.
Ethyl 2-(5-bromobenzo[b]thiophen-3-yl)acetate (CAS 17266-44-3), molecular formula C12H11BrO2S and molecular weight 299.18 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-(5-bromobenzo[b]thiophen-3-yl)acetate (C12H11BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.
CATO manufactures Ethyl 2-(5-bromobenzo[b]thiophen-3-yl)acetate 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.
