Description
Summary:The crystal structure of the hydrated form of 7-chloro-4-(4-methyl-1-piperazinyl)quinoline (<b>BPIP</b>) was determined by single-crystal X-ray diffraction analysis. This study revealed a one-dimensional supramolecular network stabilized by hydrogen bonding interactions between <b>BPIP</b> and water molecules. This compound represents one-half of a piperaquine molecule, a member of the 4-aminoquinoline class of antimalarial treatments, currently employed as a partner agent in modern combination therapies. As a simplified structural analog, <b>BPIP</b> can serve as a critical model system for probing the intermolecular interactions, physicochemical properties, and structural behavior of the parent compound. As a result, conducting a thorough solid-state characterization of <b>BPIP</b> is critical for gaining insight into its physical properties and verifying the material’s identity and purity.
