Description

Compared with other compounds in its class, the molecular weight of 310.35 g/mol gives 3-Ethyl-4-(2-phenoxyacetyl)-1,2,3,4-tetrahydroquinoxalin-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Ethyl-4-(2-phenoxyacetyl)-1,2,3,4-tetrahydroquinoxalin-2-one (CAS 1007921-18-7), a certified reference material (molecular formula C18H18N2O3, MW 310.35 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-Ethyl-4-(2-phenoxyacetyl)-1,2,3,4-tetrahydroquinoxalin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
