Chemical Structure
Description
The molecular framework of 1-(2,2,6,6-Tetramethyl-4-{[(phenylsulfonyl)oxy]imino}piperidino)-1-ethanone (C17H24N2O4S) is characterized by a flavonoid core, an amide group, a sulfone 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).
1-(2,2,6,6-Tetramethyl-4-{[(phenylsulfonyl)oxy]imino}piperidino)-1-ethanone (CAS 478079-97-9), molecular formula C17H24N2O4S and molecular weight 352.45 g/mol, is a CATO reference standard with documented purity and traceability.
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.
