Chemical Structure
Description
The occurrence of Ethyl 2-oxo-2-(4-(trifluoromethyl)phenyl)acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 2-oxo-2-(4-(trifluoromethyl)phenyl)acetate (CAS 73790-06-4) is a high-purity analytical reference standard with the molecular formula C11H9F3O3 and a molecular weight of 246.18 g/mol.
Structurally, Ethyl 2-oxo-2-(4-(trifluoromethyl)phenyl)acetate (C11H9F3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 246.18 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.
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.
