Description
CATO manufactures 4,6-Dibromo-1-chloroisoquinoline 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.
4,6-Dibromo-1-chloroisoquinoline (CAS 1254514-17-4) is a high-purity analytical reference standard with the molecular formula C9H4Br2ClN and a molecular weight of 321.40 g/mol.
4,6-Dibromo-1-chloroisoquinoline (C9H4Br2ClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
