Used in organic synthesis as a chiral building block for pharmaceuticals, particularly in the development of centrally acting agents targeting neurological pathways. Its constrained cyclobutane structure with defined stereochemistry makes it valuable for designing enzyme inhibitors and receptor modulators. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid backbone and functional group compatibility. Also utilized in the preparation of bioactive molecules where small ring systems enhance metabolic stability and target selectivity.
