Description

Compared with other compounds in its class, the molecular weight of 315.41 g/mol gives 5-Ethyl-3-(((5-ethyl-2-methoxy-6-methylpyridin-3-yl)methyl)amino)-6-methylpyridin-2(1H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Ethyl-3-(((5-ethyl-2-methoxy-6-methylpyridin-3-yl)methyl)amino)-6-methylpyridin-2(1H)-one (CAS 139547-89-0), molecular formula C18H25N3O2 and molecular weight 315.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Ethyl-3-(((5-ethyl-2-methoxy-6-methylpyridin-3-yl)methyl)amino)-6-methylpyridin-2(1H)-one (C18H25N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
