Chemical Structure

4-Methyl-3-(2,2,2-trifluoroacetyl)quinolin-2(1H)-one CAS 727-58-2 chemical structure

Description

The occurrence of 4-Methyl-3-(2,2,2-trifluoroacetyl)quinolin-2(1H)-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.

CATO supplies 4-Methyl-3-(2,2,2-trifluoroacetyl)quinolin-2(1H)-one (CAS 727-58-2), a certified reference material (molecular formula C12H8F3NO2, MW 255.19 g/mol) for analytical method development and quality control.

Structurally, 4-Methyl-3-(2,2,2-trifluoroacetyl)quinolin-2(1H)-one (C12H8F3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 255.19 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 4-Methyl-3-(2,2,2-trifluoroacetyl)quinolin-2(1H)-one 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.
