Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.65 g/mol gives 3-Chloro-9H-Carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloro-9H-Carbazole (CAS 2732-25-4), molecular formula C12H8ClN and molecular weight 201.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H8ClN, 3-Chloro-9H-Carbazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 201.65 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
