Used as a key building block in peptide synthesis and bioconjugation, this compound enables the introduction of a protected amine functionality at the ω-end of a long aliphatic chain. Its carboxylic acid and Boc-protected amine groups allow for sequential coupling reactions, making it ideal for spacer or linker design in pharmaceuticals, surface functionalization, and dendrimer construction. The 12-carbon chain provides flexibility and hydrophobic character, useful in modifying drug delivery systems or enhancing membrane permeability in bioactive molecules.
