Chemical Structure

2-(3-Bromophenyl)-9,9-dimethyl-9H-fluorene CAS 881912-14-7 chemical structure

Description

The occurrence of 2-(3-Bromophenyl)-9,9-dimethyl-9H-fluorene is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(3-Bromophenyl)-9,9-dimethyl-9H-fluorene (CAS 881912-14-7), a certified reference material (molecular formula C21H17Br, MW 349.26 g/mol) for analytical method development and quality control.

2-(3-Bromophenyl)-9,9-dimethyl-9H-fluorene (C21H17Br) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 2-(3-Bromophenyl)-9,9-dimethyl-9H-fluorene 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.
