TCI B6522 Bicyclo[1.1.1]pentane-1,3-dicarboxylic Acid (CAS 56842-95-6) is a rigid, three-dimensional building block widely used in modern medicinal chemistry. The bicyclo[1.1.1]pentane core is frequently explored as a bioisostere for para-substituted benzene rings, offering a fixed linear vector between substituents. Its two bridgehead carboxylic acids can be converted into esters, amides, and rigid linkers for further elaboration. Supplied in a 1 g research pack, it should be weighed in a well-ventilated area and stored cool, dry, and tightly sealed.
