3-(4-Fluorophenyl)-2-methyl-4-oxo-4-phenylbutanoic acid CAS 866043-52-9

Description

The occurrence of 3-(4-Fluorophenyl)-2-methyl-4-oxo-4-phenylbutanoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Fluorophenyl)-2-methyl-4-oxo-4-phenylbutanoic acid (CAS 866043-52-9) is a high-purity analytical reference standard with the molecular formula C17H15FO3 and a molecular weight of 286.30 g/mol.

3-(4-Fluorophenyl)-2-methyl-4-oxo-4-phenylbutanoic acid (C17H15FO3) contains a steroid core, 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.
