N-Boc-PEG7-alcohol is widely used in the field of bioconjugation and drug delivery systems. Its polyethylene glycol (PEG) chain provides excellent water solubility and biocompatibility, making it ideal for modifying peptides, proteins, or small molecules to enhance their pharmacokinetic properties. The Boc (tert-butoxycarbonyl) protecting group allows for selective deprotection, enabling controlled functionalization in synthetic chemistry. This compound is particularly valuable in the development of prodrugs, where it can act as a linker to improve drug stability and targeted delivery. Additionally, it is employed in the synthesis of PEGylated compounds, which are crucial in reducing immunogenicity and prolonging the circulation time of therapeutic agents in the body. Its versatility also extends to material science, where it is used to create hydrophilic coatings or functionalized surfaces for biomedical applications.
