Description
Compared with other compounds in its class, the molecular weight of 230.18 g/mol gives 1-[3-(Trifluoromethyl)phenyl]butane-1,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-[3-(Trifluoromethyl)phenyl]butane-1,3-dione (CAS 55655-84-0), a certified reference material (molecular formula C11H9F3O2, MW 230.18 g/mol) for analytical method development and quality control.
1-[3-(Trifluoromethyl)phenyl]butane-1,3-dione (C11H9F3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1-[3-(Trifluoromethyl)phenyl]butane-1,3-dione 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.
