Description
As a certified reference material (CRM), 3-(2,2,2-Trifluoroacetyl)dihydrofuran-2(3H)-one 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.
CATO supplies 3-(2,2,2-Trifluoroacetyl)dihydrofuran-2(3H)-one (CAS 69243-04-5), a certified reference material (molecular formula C6H5F3O3, MW 182.10 g/mol) for analytical method development and quality control.
The molecular framework of 3-(2,2,2-Trifluoroacetyl)dihydrofuran-2(3H)-one (C6H5F3O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
