alphamethadol

It is an isomer of dimepheptanol (methadol), the other being alphamethadol (α-methadol).

Dimepheptanol is a mixture of two isomers, alphamethadol (α-methadol) and betamethadol (β-methadol).

Both of alphamethadol's isomers bind to and activate the μ-opioid receptor and are active as opioid analgesics, similarly to those of alphacetylmethadol (α-acetylmethadol).
