4,4-Diethoxy-1,1,1-trifluoro-3-buten-2-one (CAS 40657-29-2), molecular formula C8H11F3O3 and molecular weight 212.17 g/mol, is a CATO reference standard with documented purity and traceability.
4,4-Diethoxy-1,1,1-trifluoro-3-buten-2-one (C8H11F3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4,4-Diethoxy-1,1,1-trifluoro-3-buten-2-one 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.
