4-Benzylidene-2-(trifluoromethyl)oxazol-5(4H)-one CAS 617-24-3

Description

The occurrence of 4-Benzylidene-2-(trifluoromethyl)oxazol-5(4H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Benzylidene-2-(trifluoromethyl)oxazol-5(4H)-one (CAS 617-24-3), molecular formula C11H6F3NO2 and molecular weight 241.17 g/mol, is a CATO reference standard with documented purity and traceability.

4-Benzylidene-2-(trifluoromethyl)oxazol-5(4H)-one (C11H6F3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
