Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4,6-dioxo-6-(4'-(trifluoromethyl)biphenyl-4-yl)hexanoate.
CATO supplies Ethyl 4,6-dioxo-6-(4'-(trifluoromethyl)biphenyl-4-yl)hexanoate (CAS 1455432-16-2), a certified reference material (molecular formula C21H19F3O4, MW 392.37 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H19F3O4, Ethyl 4,6-dioxo-6-(4'-(trifluoromethyl)biphenyl-4-yl)hexanoate contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 392.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
