Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 505.37 g/mol gives Quinazoline-2,4-dithiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Quinazoline-2,4-dithiol (CAS 60397-89-9) is a high-purity analytical reference standard with the molecular formula C16H17FN5O9PS and a molecular weight of 505.37 g/mol.
Quinazoline-2,4-dithiol (C16H17FN5O9PS) contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
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.
