2-chloro-7-nitro-3,4-dihydroquinazolin-4-one CAS 129112-64-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-chloro-7-nitro-3,4-dihydroquinazolin-4-one (CAS 129112-64-7) is a high-purity analytical reference standard with the molecular formula C8H12ClN3O3 and a molecular weight of 233.65 g/mol.

Based on its molecular formula C8H12ClN3O3, 2-chloro-7-nitro-3,4-dihydroquinazolin-4-one 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 233.65 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 2-chloro-7-nitro-3,4-dihydroquinazolin-4-one 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.
