This chemical is widely used in bioconjugation and drug delivery systems due to its reactive aldehyde group, which allows for efficient coupling with amino groups in proteins, peptides, or other biomolecules. It is particularly valuable in the development of PEGylated therapeutics, where it enhances solubility, stability, and circulation time of drugs. Additionally, it is employed in the synthesis of crosslinkers for creating hydrogels or modifying surfaces for biomedical applications. Its role in improving the pharmacokinetics and reducing immunogenicity of therapeutic agents makes it a key component in advanced pharmaceutical research and development.
