Chemical Structure

2-Bromo-9-methyl-9-phenyl-9H-fluorene CAS 1548450-68-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 335.24 g/mol gives 2-Bromo-9-methyl-9-phenyl-9H-fluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Bromo-9-methyl-9-phenyl-9H-fluorene (CAS 1548450-68-5), a certified reference material (molecular formula C20H15Br, MW 335.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C20H15Br, 2-Bromo-9-methyl-9-phenyl-9H-fluorene contains bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 335.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 2-Bromo-9-methyl-9-phenyl-9H-fluorene 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.
