Chemical Structure
Description
The occurrence of 3,4,5,6-Tetrabromo-1,2-benzoquinone Standard is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,4,5,6-Tetrabromo-1,2-benzoquinone Standard (CAS 2435-54-3), molecular formula C6Br4O2 and molecular weight 423.68 g/mol, is a CATO reference standard with documented purity and traceability.
3,4,5,6-Tetrabromo-1,2-benzoquinone Standard (C6Br4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 3,4,5,6-Tetrabromo-1,2-benzoquinone Standard 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.
