Chemical Structure
Description
Methyl (E)-3-((4,4,4-trifluoro-3-oxobut-1-en-1-yl)amino)thiophene-2-carboxylate (CAS 672949-73-4), molecular formula C10H8F3NO3S and molecular weight 279.24 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl (E)-3-((4,4,4-trifluoro-3-oxobut-1-en-1-yl)amino)thiophene-2-carboxylate (C10H8F3NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Methyl (E)-3-((4,4,4-trifluoro-3-oxobut-1-en-1-yl)amino)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.
