Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 336.02 g/mol gives 1,5-Dibromoanthracene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,5-Dibromoanthracene (CAS 3278-82-8) is a high-purity analytical reference standard with the molecular formula C14H8Br2 and a molecular weight of 336.02 g/mol.
1,5-Dibromoanthracene (C14H8Br2) contains bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1,5-Dibromoanthracene 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.
