Chemical Structure
Description
CATO supplies Ethyl 2-(trifluoroacetamido)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (CAS 171734-43-3), a certified reference material (molecular formula C13H14F3NO3S, MW 321.32 g/mol) for analytical method development and quality control.
Ethyl 2-(trifluoroacetamido)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (C13H14F3NO3S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 2-(trifluoroacetamido)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
