Chemical Structure
Description
2-[(2-{[(2-chlorophenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazolin-4-yl)sulfanyl]acetic acid (C17H17ClN2O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
2-[(2-{[(2-chlorophenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazolin-4-yl)sulfanyl]acetic acid (CAS 339019-39-5) is a high-purity analytical reference standard with the molecular formula C17H17ClN2O2S2 and a molecular weight of 380.91 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.
