Used in peptide synthesis as a protecting group for the amino group of D-threonine, ensuring selective reactions during the formation of peptide bonds. It is particularly valuable in the production of complex peptides and proteins, where precise control over amino acid reactivity is essential. The tert-butoxycarbonyl (Boc) group can be easily removed under mild acidic conditions, making it a versatile tool in organic and medicinal chemistry. This compound is also employed in the development of pharmaceuticals, especially in the synthesis of bioactive peptides and peptidomimetics, where the stereochemistry and purity of amino acids are critical for biological activity.
