Methoxy-Tr-NH-PEG7 is widely used in the field of bioconjugation and drug delivery due to its polyethylene glycol (PEG) chain, which enhances solubility and biocompatibility. It is often employed to modify proteins, peptides, and other biomolecules, improving their stability and reducing immunogenicity. This compound is particularly useful in creating PEGylated therapeutics, which have prolonged circulation times in the body, making them more effective for targeted treatments. Additionally, it is utilized in the development of diagnostic agents and imaging probes, where its PEG chain helps in reducing nonspecific interactions and improving signal clarity. In research, Methoxy-Tr-NH-PEG7 is also applied in the synthesis of advanced materials and nanoparticles, where it acts as a linker or spacer to control the distance between functional groups, enhancing the performance of the final product.
