(S)-5-Fluoro-2,3-dihydro-1H-inden-1-amine hydrochloride is primarily used in pharmaceutical research and development, particularly in the study of central nervous system (CNS) disorders. It serves as a key intermediate or active pharmaceutical ingredient (API) in the synthesis of compounds targeting neurological conditions such as depression, anxiety, and other mood-related disorders. Its structural properties make it valuable for designing drugs that interact with specific receptors in the brain, potentially leading to the development of more effective therapeutic agents. Additionally, it may be utilized in preclinical studies to evaluate pharmacological activity, safety, and efficacy in drug discovery pipelines.
