Chemical Structure
Description
3-(3-Chloro-4-fluorophenyl)-2-mercaptoquinazolin-4(3h)-one (CAS 661477-74-3) is a high-purity analytical reference standard with the molecular formula C14H8ClFN2OS and a molecular weight of 306.74 g/mol.
3-(3-Chloro-4-fluorophenyl)-2-mercaptoquinazolin-4(3h)-one (C14H8ClFN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, 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.
