4,4,4-Trifluoro-2-(4-methoxyphenyl)-3-oxobutanenitrile CAS 22102-05-2

Description

Compared with other compounds in its class, the molecular weight of 243.18 g/mol gives 4,4,4-Trifluoro-2-(4-methoxyphenyl)-3-oxobutanenitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4,4-Trifluoro-2-(4-methoxyphenyl)-3-oxobutanenitrile (CAS 22102-05-2), molecular formula C11H8F3NO2 and molecular weight 243.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4,4-Trifluoro-2-(4-methoxyphenyl)-3-oxobutanenitrile (C11H8F3NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
