5,9-dibromo-7,7-dimethyl-7H-Benzo[c]fluorene CAS 1056884-35-5

Description

The occurrence of 5,9-dibromo-7,7-dimethyl-7H-Benzo[c]fluorene is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5,9-dibromo-7,7-dimethyl-7H-Benzo[c]fluorene (CAS 1056884-35-5) is a high-purity analytical reference standard with the molecular formula C19H14Br2 and a molecular weight of 402.12 g/mol.

Owing to bromine substitution, a polycyclic aromatic system, 5,9-dibromo-7,7-dimethyl-7H-Benzo[c]fluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
