Chemical Structure
Description
Based on its molecular formula C13H8Cl2, 2,7-Dichloro-9H-fluorene contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 235.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
2,7-Dichloro-9H-fluorene (CAS 7012-16-0), molecular formula C13H8Cl2 and molecular weight 235.11 g/mol, is a CATO reference standard with documented purity and traceability.
