Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 287.94 g/mol gives 3,7-Dibromocinnoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,7-Dibromocinnoline (CAS 1956370-82-3) is a high-purity analytical reference standard with the molecular formula C8H4Br2N2 and a molecular weight of 287.94 g/mol.
3,7-Dibromocinnoline (C8H4Br2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
CATO manufactures 3,7-Dibromocinnoline 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.
