3-[4-(trifluoromethyl)phenyl]but-2-enoic acid CAS 7386-61-0

Description

3-[4-(trifluoromethyl)phenyl]but-2-enoic acid (CAS 7386-61-0), molecular formula C11H9F3O2 and molecular weight 230.18 g/mol, is a CATO reference standard with documented purity and traceability.

3-[4-(trifluoromethyl)phenyl]but-2-enoic acid (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.

As a certified reference material (CRM), 3-[4-(trifluoromethyl)phenyl]but-2-enoic acid 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.
