Application

Thebaine has been used for the synthesis of neopinone/codeinone ring systems. Thebaine has also been used as a 1 mg/ml standard in methanol for urine thebaine analysis in individuals who had consumed poppy seeds.

Biochem/physiol Actions

The (-)-isomer of thebaine is the naturally-occurring constituent of opium that is a precursor of morphine. It has poor antinociceptive activity and induces convulsions. It binds to μ and δ opioid receptors in vitro.

Physical form

Alkaloid powder

Preparation Note

Thebaine dissolves in chloroform at 50 mg/ml to yield a clear, yellow solution. It soluble in alcohol, ether, and benzene at 1:10, 1: 135, and 1:18 parts respectively. However, thebaine does not dissolve in water.
