Description

Compared with other compounds in its class, the molecular weight of 256.25 g/mol gives 2-(4-Oxo-3,4-dihydroquinazolin-3-yl)ethane-1-sulfonyl fluoride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(4-Oxo-3,4-dihydroquinazolin-3-yl)ethane-1-sulfonyl fluoride (CAS 885528-94-9), a certified reference material (molecular formula C10H9FN2O3S, MW 256.25 g/mol) for analytical method development and quality control.

2-(4-Oxo-3,4-dihydroquinazolin-3-yl)ethane-1-sulfonyl fluoride (C10H9FN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
