Used primarily as a reagent in organic synthesis, particularly in the protection of alcohols and amines during multi-step reactions. Its reactivity allows it to form carbonate or carbamate derivatives, which are stable under various reaction conditions but can be selectively removed when needed. Commonly employed in pharmaceutical synthesis where selective functional group manipulation is required. Also utilized in peptide chemistry to prevent unwanted side reactions by blocking reactive sites. Suitable for moisture-sensitive reactions due to its ability to form stable intermediates under anhydrous conditions.
