Citalopram N-Oxide HCl is a piperazine-based N-oxide derivative of the parent SSRI citalopram, featuring a dibenzofazan core with an oxidized nitrogen atom at the piperazine ring. The hydrochloride salt formation protonates the piperazine nitrogen, enhancing water solubility compared to the parent compound. This impurity arises via oxidative metabolism or synthetic pathway side reactions, differing from citalopram by the N-oxide substitution. Utilized as an HPLC reference standard for quantifying process-related impurities in citalopram APIs.
