Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 305.99 g/mol gives 7-Bromo-2,4-dichloro-6-ethylquinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 7-Bromo-2,4-dichloro-6-ethylquinazoline (CAS 2771459-73-3), a certified reference material (molecular formula C10H7BrCl2N2, MW 305.99 g/mol) for analytical method development and quality control.
7-Bromo-2,4-dichloro-6-ethylquinazoline (C10H7BrCl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-Bromo-2,4-dichloro-6-ethylquinazoline 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.
