Chemical Structure
Description
Based on its molecular formula C19H32, 5β-ANDROSTANE contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.46 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).
5β-ANDROSTANE (CAS 438-23-3), molecular formula C19H32 and molecular weight 260.46 g/mol, is a CATO reference standard with documented purity and traceability.
