Chemical Structure
Description
6,7-Dimethoxy-2-((3-methoxybenzyl)thio)-3-octylquinazolin-4(3H)-imine (C26H35N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
6,7-Dimethoxy-2-((3-methoxybenzyl)thio)-3-octylquinazolin-4(3H)-imine (CAS 860789-62-4) is a high-purity analytical reference standard with the molecular formula C26H35N3O3S and a molecular weight of 469.64 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.
