Description

Compared with other compounds in its class, the molecular weight of 286.33 g/mol gives Ethyl 2-[4-(cyclopropylmethyl)-3-oxo-3,4-dihydroquinoxalin-2-yl]acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-[4-(cyclopropylmethyl)-3-oxo-3,4-dihydroquinoxalin-2-yl]acetate (CAS 478041-10-0) is a high-purity analytical reference standard with the molecular formula C16H18N2O3 and a molecular weight of 286.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Ethyl 2-[4-(cyclopropylmethyl)-3-oxo-3,4-dihydroquinoxalin-2-yl]acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
