Chemical Structure
Description
The occurrence of 2-Bromo-9-phenyl-9H-fluoren-9-ol is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-9-phenyl-9H-fluoren-9-ol (CAS 736928-22-6) is a high-purity analytical reference standard with the molecular formula C19H13BrO and a molecular weight of 337.21 g/mol.
The molecular framework of 2-Bromo-9-phenyl-9H-fluoren-9-ol (C19H13BrO) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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).
