Used as an efficient acylating agent for the introduction of the benzoyl protecting group in organic synthesis, particularly in peptide synthesis. It enables selective acylation of amino groups in amino acids and peptides under mild conditions. Commonly applied in the preparation of protected intermediates for pharmaceuticals and bioactive molecules. Also utilized in the formation of benzoyl esters and amides from alcohols and amines, making it valuable in the development of peptide-based drugs and fine chemicals.
