Compared with other compounds in its class, the molecular weight of 353.43 g/mol gives 868273-09-0 N-{2-[4-(Dimethylamino)phenyl]ethyl}-3-ethyl-5-fluoro-1H-indole-2-carboxamide DTXSID80720951 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
868273-09-0 N-{2-[4-(Dimethylamino)phenyl]ethyl}-3-ethyl-5-fluoro-1H-indole-2-carboxamide DTXSID80720951 (CAS 868273-09-0), molecular formula C21H24FN3O and molecular weight 353.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 868273-09-0 N-{2-[4-(Dimethylamino)phenyl]ethyl}-3-ethyl-5-fluoro-1H-indole-2-carboxamide DTXSID80720951 (C21H24FN3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
