Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer therapy. Its structure allows for selective modification to enhance binding affinity to specific enzyme targets. Commonly employed in research settings to design bioactive molecules with improved metabolic stability and solubility. Also utilized in the preparation of receptor modulators for neurological disorders due to the presence of the piperazine moiety, which is known to influence blood-brain barrier penetration and binding to neurotransmitter receptors such as serotonin, dopamine, and norepinephrine, aiding in treatments for psychiatric conditions like depression, anxiety, and schizophrenia.
