Chemical Structure
Description
The occurrence of 5,5,5-Trifluoropent-3-en-2-one is closely related to a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5,5,5-Trifluoropent-3-en-2-one (CAS 75747-61-4), molecular formula C5H5F3O and molecular weight 138.09 g/mol, is a CATO reference standard with documented purity and traceability.
5,5,5-Trifluoropent-3-en-2-one (C5H5F3O) contains a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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 5,5,5-Trifluoropent-3-en-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.
