Chemical Structure
Description
The occurrence of 5,6-Dihydrobenzo[h]quinazoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5,6-Dihydrobenzo[h]quinazoline (CAS 34773-06-3), a certified reference material (molecular formula C12H10N2, MW 182.22 g/mol) for analytical method development and quality control.
5,6-Dihydrobenzo[h]quinazoline (C12H10N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
CATO manufactures 5,6-Dihydrobenzo[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.
