Betamethadol
Betamethadol, or β-methadol, also known as betametadol, is a synthetic opioid analgesic. It is an isomer of dimepheptanol, the other being alphamethadol. Betamethadol is composed of two isomers itself, L-β-methadol, and D-β-methadol. Based on structure-activity relationships it can be inferred that both isomers are likely to be active as opioid analgesics, similarly to those of betacetylmethadol.
