Chemical Structure
Description
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.
1-(Tert-butyl)-3-(1-(2,6-dichlorobenzyl)-6-oxo-1,6-dihydropyridin-3-yl)urea (CAS 338784-99-9) is a high-purity analytical reference standard with the molecular formula C17H19Cl2N3O2 and a molecular weight of 368.26 g/mol.
The molecular framework of 1-(Tert-butyl)-3-(1-(2,6-dichlorobenzyl)-6-oxo-1,6-dihydropyridin-3-yl)urea (C17H19Cl2N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
