10α-Methoxy-9,10-dihydrolysergol D5 (D5 Major)

10α-Methoxy-9,10-dihydrolysergol D5, commonly known as D5 Major, is a chemical compound that belongs to the ergoline family of alkaloids. It is a derivative of lysergic acid and is structurally similar to other ergoline alkaloids such as LSD and ergotamine. D5 Major is a potent agonist of serotonin receptors, particularly the 5-HT2A subtype, which is responsible for its psychoactive effects. D5 Major has been used in scientific research to study the pharmacological effects of serotonin receptor agonists. It has also been investigated for its potential therapeutic applications in the treatment of mental health disorders such as depression, anxiety, and addiction. However, its psychoactive effects and potential for abuse have limited its clinical use. The chemical formula of D5 Major is C20H25N3O2 and its molecular weight is 339.44 g/mol. It has a melting point of 200-202°C and a solubility of 10 mg/mL in ethanol. D5 Major is typically synthesized through a multi-step process that involves the reaction of lysergic acid with various reagents. While D5 Major has been studied extensively in the laboratory, its use outside of research is highly discouraged due to its psychoactive effects and potential for abuse. It is important to handle D5 Major with caution and to dispose of it properly to prevent harm to individuals and the environment.
