Chemical Structure
Description
The occurrence of 2-Amino-6-(naphthalen-2-ylsulfinyl)quinazolin-4(1H)-one is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Amino-6-(naphthalen-2-ylsulfinyl)quinazolin-4(1H)-one (CAS 52979-10-9) is a high-purity analytical reference standard with the molecular formula C18H13N3O2S and a molecular weight of 335.38 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-Amino-6-(naphthalen-2-ylsulfinyl)quinazolin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
