2,7-Dibromofluorene CAS 16433-88-8 chemical structure

Description

CATO supplies 2,7-Dibromofluorene (CAS 16433-88-8), a certified reference material (molecular formula C13H8Br2, MW 324.01 g/mol) for analytical method development and quality control.

2,7-Dibromofluorene (C13H8Br2) contains bromine substitution, an aromatic ring 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,7-Dibromofluorene 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.
