Chemical Structure
Description
Based on its molecular formula C13H19NO2, 4-(tert-Butyl)-DL-phenylalanine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.30 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).
4-(tert-Butyl)-DL-phenylalanine (CAS 98708-80-6), molecular formula C13H19NO2 and molecular weight 221.30 g/mol, is a CATO reference standard with documented purity and traceability.
