Chemical Structure
Description
6-(3,4-Dichlorophenyl)-2-methyl-5H,6H-benzo[h]quinazoline (CAS 866018-50-0), molecular formula C19H14Cl2N2 and molecular weight 341.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 6-(3,4-Dichlorophenyl)-2-methyl-5H,6H-benzo[h]quinazoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 6-(3,4-Dichlorophenyl)-2-methyl-5H,6H-benzo[h]quinazoline 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.
