Boc-Cys(tBu)-OH, also known as N-tert-butoxycarbonyl-L-cysteine, is a valuable building block in chemical synthesis due to its versatility and compatibility with various synthetic processes. In peptide synthesis, Boc-Cys(tBu)-OH serves as a protected form of the amino acid cysteine, providing stability to the sulfhydryl group and facilitating the selective deprotection of the Boc group under mild conditions. This enables the precise incorporation of cysteine into peptides and proteins without unwanted side reactions. Additionally, Boc-Cys(tBu)-OH is commonly used in the preparation of thioesters, which are important intermediates in the synthesis of complex molecules such as peptides, peptidomimetics, and small molecule drugs. Its ease of handling and compatibility with standard peptide coupling reagents make Boc-Cys(tBu)-OH a valuable tool for the synthesis of diverse bioactive compounds and chemical probes.
