  • Applications

    Harmaline Hydrochloride Dihydrate is primarily encountered in pharmaceutical and biochemical research. It is used as a pharmacological tool and as an MAO-inhibitor analogue in studies of enzyme inhibition and beta-carboline chemistry, and serves as a reference material for natural product isolation and analytical method development. In organic synthesis, the compound can function as an intermediate or building block for the preparation of beta-carboline derivatives. It may be used in quality control and standardization of natural extracts containing harmala alkaloids. Depending on formulation and local regulations, its use is typically limited to laboratory research environments.
