Benzenepropanoic acid, 5-fluoro-2-methoxy-β-oxo-, methyl ester CAS 1226233-97-1

Description

Based on its molecular formula C11H11FO4, Benzenepropanoic acid, 5-fluoro-2-methoxy-β-oxo-, methyl ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies Benzenepropanoic acid, 5-fluoro-2-methoxy-β-oxo-, methyl ester (CAS 1226233-97-1), a certified reference material (molecular formula C11H11FO4, MW 226.20 g/mol) for analytical method development and quality control.

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.
