Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding to enzyme active sites, enhancing drug efficacy. Commonly employed in medicinal chemistry for building bioactive molecules due to the stability and metabolic resistance provided by the cyclobutane and nitrile groups. Also utilized in the preparation of fluorinated analogs to improve pharmacokinetic properties such as absorption and half-life.
