N,N-Dimethyl-8-phenyl-1,4-dioxaspiro[4.5]decan-8-amine is an intermediate used in the synthesis of Cebranopadol (C228810), which can be obtained from 1,4-Cyclohexanedione Monoethylene Acetal (C987955) which is used in the preparation of series of potent analgesic compounds. 1,4-Cyclohexanedione Monoethylene Acetal (C987955) is also used as a building block in the synthesis of tritium labelled probes for the autoradiography study of the dopamine reuptake complex.
