This chemical is widely used in the field of bioconjugation and drug delivery due to its PEG (polyethylene glycol) spacer, which enhances solubility and reduces immunogenicity. It is particularly useful in linking bioactive molecules, such as peptides or proteins, to other compounds or surfaces while maintaining their stability and activity. The T-Boc protecting group allows for selective deprotection, enabling controlled reactions in multi-step synthesis. Its carboxylic acid end group facilitates further functionalization, making it valuable in creating targeted drug delivery systems, bioconjugates, or probes for diagnostic applications. Additionally, it is employed in the development of hydrogels and biomaterials for tissue engineering, where its biocompatibility and water solubility are advantageous.
