Used in pharmaceutical research as a deuterated analog for metabolic stability studies, particularly in the development of central nervous system agents. The compound's structure supports investigation into serotonin and dopamine receptor modulation, making it valuable in early-stage drug discovery for psychiatric disorders. Deuterium substitution enhances half-life and bioavailability, allowing for improved pharmacokinetic profiling. It also serves as an internal standard in mass spectrometry due to its distinct isotopic signature, aiding in accurate quantification of related non-deuterated compounds in biological matrices.
