Used primarily as a reagent in organic synthesis, particularly for introducing the tert-butoxycarbonyl (Boc) protecting group to amines. It enables selective protection under mild conditions, which is crucial in peptide and pharmaceutical synthesis. Its high reactivity and volatility make it suitable for reactions where clean deprotection is required. Also employed in the preparation of fluorinated compounds due to the trifluoromethyl group transfer capability. Commonly used in the development of agrochemicals, medicinal intermediates, and specialty polymers.
