Chemical Structure

3-methyl-7-(trifluoromethyl)-3,4-dihydro-1H-quinoxalin-2-one CAS 146741-08-4 chemical structure

Description

The occurrence of 3-methyl-7-(trifluoromethyl)-3,4-dihydro-1H-quinoxalin-2-one is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-methyl-7-(trifluoromethyl)-3,4-dihydro-1H-quinoxalin-2-one (CAS 146741-08-4) is a high-purity analytical reference standard with the molecular formula C10H15F3N2O and a molecular weight of 236.23 g/mol.

Structurally, 3-methyl-7-(trifluoromethyl)-3,4-dihydro-1H-quinoxalin-2-one (C10H15F3N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 236.23 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.

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.
