Used primarily as a deprotecting agent in organic synthesis, it selectively removes protecting groups from molecules, enabling the continuation of complex chemical reactions. Its application is crucial in peptide synthesis, where it helps in the stepwise assembly of amino acids without disrupting the integrity of the peptide chain. Additionally, it finds use in the preparation of pharmaceuticals, where precise deprotection is necessary to achieve the desired drug structure. Its efficiency and specificity make it a valuable tool in the development of active pharmaceutical ingredients (APIs) and other fine chemicals.
