Chemical Structure
Description
7-Chloro-2-(p-tolyl)quinazolin-4(1H)-one (CAS 90362-97-3) is a high-purity analytical reference standard with the molecular formula C15H11ClN2O and a molecular weight of 270.71 g/mol.
7-Chloro-2-(p-tolyl)quinazolin-4(1H)-one (C15H11ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 7-Chloro-2-(p-tolyl)quinazolin-4(1H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
