Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Benzyl-2-(pentylthio)quinazolin-4(3H)-one.
3-Benzyl-2-(pentylthio)quinazolin-4(3H)-one (CAS 25467-53-2) is a high-purity analytical reference standard with the molecular formula C20H22N2OS and a molecular weight of 338.47 g/mol.
3-Benzyl-2-(pentylthio)quinazolin-4(3H)-one (C20H22N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
