Chemical Structure
Description
CATO supplies 2-((4-Oxo-3-(p-tolyl)-3,4-dihydroquinazolin-2-yl)thio)acetohydrazide (CAS 37029-36-0), a certified reference material (molecular formula C17H16N4O2S, MW 340.40 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((4-Oxo-3-(p-tolyl)-3,4-dihydroquinazolin-2-yl)thio)acetohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
