H-Lys(ivdde)-OH

H-Lys(ivdde)-OH is a protected lysine derivative used as a building block in peptide synthesis. Its structure features a lysine residue with the amino group side-chain protected by an ivdde (1-(2-hydroxy-4,4-dimethyl-6-oxocyclohexen-1-yl)-3-methylbutylidene) group, enabling selective deprotection during solid-phase peptide assembly.
