Chemical Structure
Description
2,4-Dichloro-5-iodoquinazoline (CAS 959237-30-0) is a high-purity analytical reference standard with the molecular formula C8H3Cl2IN2 and a molecular weight of 324.93 g/mol.
Based on its molecular formula C8H3Cl2IN2, 2,4-Dichloro-5-iodoquinazoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.93 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).
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 2,4-Dichloro-5-iodoquinazoline 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.
