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 n-Ethyl-2-(thiophen-2-yl)quinazolin-4-amine.
n-Ethyl-2-(thiophen-2-yl)quinazolin-4-amine (CAS 794562-74-6) is a high-purity analytical reference standard with the molecular formula C14H13N3S and a molecular weight of 255.34 g/mol.
n-Ethyl-2-(thiophen-2-yl)quinazolin-4-amine (C14H13N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
