1-(3-Dimethylaminopropyl)-1-(4-fluorophenyl)-1,3-dihydroisobenzofuran-5-carboxamide is a synthetic organic compound structurally analogous to citalopram, a selective serotonin reuptake inhibitor (SSRI). It differs by having a carboxamide group at the 5-position of the isobenzofuran ring instead of a carbonitrile. Primarily utilized as a research chemical and potential intermediate in pharmaceutical development for antidepressant agents, it is studied for its potential serotonin reuptake inhibitory activity, which may contribute to regulating mood and treating conditions like depression and anxiety. Not approved or commonly prescribed as an active pharmaceutical ingredient; employed in laboratory settings to explore neurotransmitter modulation and structure-activity relationships in psychotropic drugs.
