Description

Compared with other compounds in its class, the molecular weight of 367.32 g/mol gives 2-(2-Ethoxy-4-formylphenoxy)-N-[3-(trifluoromethyl)phenyl]acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2-Ethoxy-4-formylphenoxy)-N-[3-(trifluoromethyl)phenyl]acetamide (CAS 486995-03-3) is a high-purity analytical reference standard with the molecular formula C18H16F3NO4 and a molecular weight of 367.32 g/mol.

2-(2-Ethoxy-4-formylphenoxy)-N-[3-(trifluoromethyl)phenyl]acetamide (C18H16F3NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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.
