Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 397.31 g/mol gives 9H-Fluorene, 3-bromo-9,9-diphenyl- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 9H-Fluorene, 3-bromo-9,9-diphenyl- (CAS 1547491-70-2), a certified reference material (molecular formula C25H17Br, MW 397.31 g/mol) for analytical method development and quality control.
The molecular framework of 9H-Fluorene, 3-bromo-9,9-diphenyl- (C25H17Br) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 9H-Fluorene, 3-bromo-9,9-diphenyl- 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.
