Description

Compared with other compounds in its class, the molecular weight of 231.25 g/mol gives 8-Ethoxy-2,3-dihydrofuro[3,2-c]quinolin-4(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

8-Ethoxy-2,3-dihydrofuro[3,2-c]quinolin-4(5H)-one (CAS 184651-20-5), molecular formula C13H13NO3 and molecular weight 231.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 8-Ethoxy-2,3-dihydrofuro[3,2-c]quinolin-4(5H)-one (C13H13NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 231.25 g/mol, it falls into the medium-molecular-weight range. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
