2-((2-Cyano-3-methylbutan-2-yl)amino)-2-oxoethyl 2-fluoro-4-methoxybenzoate CAS 871544-73-9

Description

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.

2-((2-Cyano-3-methylbutan-2-yl)amino)-2-oxoethyl 2-fluoro-4-methoxybenzoate (CAS 871544-73-9) is a high-purity analytical reference standard with the molecular formula C16H19FN2O4 and a molecular weight of 322.33 g/mol.

2-((2-Cyano-3-methylbutan-2-yl)amino)-2-oxoethyl 2-fluoro-4-methoxybenzoate (C16H19FN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
