Used primarily in organic synthesis as a building block for pharmaceuticals and specialty chemicals. Its bulky triphenylmethyl structure makes it valuable in the development of sterically hindered compounds, which can influence the stability and reactivity of drug molecules. It is also employed in the preparation of esters and amides for use in research and development, particularly in the design of enzyme inhibitors and receptor ligands. Additionally, derivatives of this acid find application in materials science, where they contribute to the creation of novel organic frameworks with unique electronic or structural properties.
