N-alpha-(tert-Butoxycarbonyl)-L-lysine Usage And Synthesis

Chemical Properties

white to off-white powder

Uses

N-Boc-L-lysine is a protected analogue of a major amino acid participating in the binding of AcH to proteins. N-Boc-L-lysine as well as other t-butoxycarbonyl (Boc) amino acids can be converted to the ir respective amino acids via cleavage of the urethane bond.
