Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7,7-Dimethyl-2-(phenylamino)-7,8-dihydroquinazolin-5(6H)-one.
7,7-Dimethyl-2-(phenylamino)-7,8-dihydroquinazolin-5(6H)-one (CAS 925015-54-9), molecular formula C16H17N3O and molecular weight 267.33 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H17N3O, 7,7-Dimethyl-2-(phenylamino)-7,8-dihydroquinazolin-5(6H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
