Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 409.32 g/mol gives 2-Bromo-9,10-diphenylanthracene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-9,10-diphenylanthracene (CAS 201731-79-5) is a high-purity analytical reference standard with the molecular formula C26H17Br and a molecular weight of 409.32 g/mol.
The molecular framework of 2-Bromo-9,10-diphenylanthracene (C26H17Br) is characterized by bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 2-Bromo-9,10-diphenylanthracene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
