Chemical Structure

6-Trifluoromethyl-1,4-dihydroquinoxaline-2,3-dione CAS 55687-31-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 6-Trifluoromethyl-1,4-dihydroquinoxaline-2,3-dione (CAS 55687-31-5), a certified reference material (molecular formula C9H5F3N2O2, MW 230.14 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H5F3N2O2, 6-Trifluoromethyl-1,4-dihydroquinoxaline-2,3-dione 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 230.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
