Used in bioconjugation and drug delivery systems, it serves as a linker to attach bioactive molecules to nanoparticles or proteins, enhancing solubility and stability. It is also employed in the synthesis of antibody-drug conjugates (ADCs) for targeted cancer therapies. Additionally, it is utilized in surface modification of materials to improve biocompatibility and in the development of hydrogels for tissue engineering applications. Its aldehyde group allows for specific and efficient reactions with amines or hydrazines, making it valuable in controlled-release drug formulations and diagnostic assays.
