Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(2-Aminoethyl)-3,4-dihydroquinazolin-4-one dihydrochloride (CAS 858236-77-8), molecular formula C10H11N3OHCl and molecular weight 225.68 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H11N3OHCl, 3-(2-Aminoethyl)-3,4-dihydroquinazolin-4-one dihydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
CATO manufactures 3-(2-Aminoethyl)-3,4-dihydroquinazolin-4-one dihydrochloride 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.
