Chemical Structure
Description
The occurrence of 2-Phenoxy-3-(trifluoromethyl)quinoxaline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Phenoxy-3-(trifluoromethyl)quinoxaline (CAS 338773-58-3), a certified reference material (molecular formula C15H9F3N2O, MW 290.24 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H9F3N2O, 2-Phenoxy-3-(trifluoromethyl)quinoxaline contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 290.24 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.
