Chemical Structure
Description
The molecular framework of (2,6-Dimethoxyphenyl)(2-((2-fluorobenzyl)thio)-4,5-dihydro-1H-imidazol-1-yl)methanone (C19H19FN2O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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).
(2,6-Dimethoxyphenyl)(2-((2-fluorobenzyl)thio)-4,5-dihydro-1H-imidazol-1-yl)methanone (CAS 851806-84-3) is a high-purity analytical reference standard with the molecular formula C19H19FN2O3S and a molecular weight of 374.43 g/mol.
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.
