3-[2-[4-(4-fluoro-2-hydroxybenzoyl)piperidin-1-yl]ethyl]-2-methyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidin-4-one hydrochloride is a chemical compound with a molecular formula of C27H31FN4O3.HCl. It is a white to off-white powder with a molecular weight of 500.02 g/mol. This compound has been shown to have potential therapeutic uses in the treatment of various conditions, including depression, anxiety, and schizophrenia. It acts as a selective serotonin reuptake inhibitor (SSRI), which means that it increases the levels of serotonin in the brain by inhibiting its reuptake. In terms of chemical structure, this compound has a piperidine ring attached to a benzoyl group, which in turn is attached to a pyrido[1,2-a]pyrimidin-4-one ring system. The presence of the fluorine and hydroxyl groups on the benzoyl ring contribute to its pharmacological activity. The hydrochloride salt form of this compound is commonly used for medicinal purposes due to its improved solubility in water. It is typically administered orally, with dosages varying depending on the specific condition being treated and the patient's individual needs.
