Chemical Structure
Description
4-(3,4-Dihydroisoquinolin-2(1H)-yl)-2-(pyridin-3-yl)quinazoline (CAS 796079-91-9), molecular formula C22H18N4 and molecular weight 338.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(3,4-Dihydroisoquinolin-2(1H)-yl)-2-(pyridin-3-yl)quinazoline (C22H18N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 4-(3,4-Dihydroisoquinolin-2(1H)-yl)-2-(pyridin-3-yl)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.
