Aminooxyacetamide-PEG-Azide is a versatile compound used in pharmaceutical research and development. It is classified as a bifunctional molecule due to the presence of two distinct functional groups: an azide group and an aminooxy group. The azide group is highly reactive and can be used for various chemical reactions such as click chemistry and bioorthogonal labeling, while the aminooxy group is commonly used for protein modification and conjugation. In pharmaceutical research and development, Aminooxyacetamide-PEG-Azide can be used for the preparation of drug delivery systems, targeted therapy, and bioconjugation. Its unique properties make it an attractive option for drug design and development as it allows for precise control over drug delivery and target specificity.
