Used primarily as a reagent in organic synthesis, particularly for introducing the butenyl carbonate protecting group for alcohols and amines. It is effective in peptide synthesis and nucleoside chemistry due to its selective reactivity and mild deprotection conditions. The compound enables the formation of carbamate and carbonate derivatives, which are useful intermediates in pharmaceutical and agrochemical manufacturing. Its allyl-like structure allows for further functionalization via cross-coupling or cyclization reactions, making it valuable in building complex organic molecules. Handle with care due to its lachrymatory and moisture-sensitive properties.
