Chemical Structure
Description
ethyl 7-bromo-4-fluoro-benzothiophene-2-carboxylate (C11H8BrFO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
ethyl 7-bromo-4-fluoro-benzothiophene-2-carboxylate (CAS 1098608-38-8) is a high-purity analytical reference standard with the molecular formula C11H8BrFO2S and a molecular weight of 303.15 g/mol.
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 7-bromo-4-fluoro-benzothiophene-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.
