Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly receptor agonists and antagonists targeting neurotransmitter receptors such as serotonin and dopamine receptors. Relevant in neuroscience-related drug discovery for central nervous system disorders, including anxiety, depression, psychosis, and cognitive diseases. Commonly employed in new drug development to optimize structure for efficacy and minimize side effects. Also used as an internal laboratory standard for analyzing structurally similar compounds. Additionally, utilized in agrochemical research for developing new active ingredients with selective biological activity.
