Chemical Structure
Description
Ethyl 2-(quinazolin-4-ylthio)acetate (CAS 7255-81-4), molecular formula C15H19NO2 and molecular weight 245.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H19NO2, Ethyl 2-(quinazolin-4-ylthio)acetate 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 245.32 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.
