Chemical Structure

3-(Trifluoromethyl)benzyl (R)-5-oxotetrahydrofuran-2-carboxylate CAS 1445700-01-5 chemical structure

Description

3-(Trifluoromethyl)benzyl (R)-5-oxotetrahydrofuran-2-carboxylate (CAS 1445700-01-5), molecular formula C13H11F3O4 and molecular weight 288.22 g/mol, is a CATO reference standard with documented purity and traceability.

3-(Trifluoromethyl)benzyl (R)-5-oxotetrahydrofuran-2-carboxylate (C13H11F3O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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), 3-(Trifluoromethyl)benzyl (R)-5-oxotetrahydrofuran-2-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.
