Used in neuroscience research to study neurotransmitter systems, particularly as a precursor in the synthesis of gamma-aminobutyric acid (GABA) analogs. It plays a role in investigating the regulation of GABAergic signaling, which is crucial for understanding neurological disorders such as epilepsy, anxiety, and depression. Additionally, it serves as a building block in the development of potential therapeutic agents targeting the central nervous system. Its indole structure makes it valuable for exploring interactions with serotonin receptors, contributing to research on mood and cognitive function.
