2-Chloromethcathinone hydrochloride (2-CMC) is primarily known for its use in research settings, particularly in the study of psychoactive substances and their effects on the central nervous system. It has been investigated for its stimulant properties, often compared to other cathinone derivatives, to understand its impact on neurotransmitter systems such as dopamine and serotonin. In some cases, it has been used recreationally, though this is not its intended purpose. Research also explores its potential risks, including addiction and adverse health effects, to contribute to the broader understanding of synthetic stimulants and their regulation.
