Acid-C1-PEG5-Boc（Cat No.:I015966）is a bifunctional polyethylene glycol linker containing a terminal carboxylic acid and a Boc-protected amine group separated by a five-unit PEG chain with a C1 spacer. The PEG segment enhances water solubility, flexibility, and reduces steric hindrance, while the Boc group provides temporary protection, enabling controlled deprotection for selective amine coupling. This structure is widely applied in bioconjugation, drug discovery, and material science for designing linkers, peptide modifications, or polymer conjugates. Acid-C1-PEG5-Boc is particularly useful for constructing multifunctional molecules and optimizing bioactive compound design.
