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 modification, making it valuable in creating bioactive molecules with improved metabolic stability. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the constrained cyclobutane ring and halogen substitutions that influence binding affinity and pharmacokinetics. Also utilized in the preparation of analogs for drug discovery programs targeting inflammatory and oncological diseases.
