Azido-PEG-succinimidyl carbonate is a chemical compound that contains several functional groups, including an azide group, a succinimidyl carbonate group, and a polyethylene glycol (PEG) chain. These functional groups make it a versatile compound that can be used in various applications, including pharmaceutical research and development. The azide group is commonly used in bioconjugation reactions to attach biomolecules, such as proteins and antibodies, to surfaces or other molecules. The succinimidyl carbonate group can react with primary amines to form stable amide bonds, making it useful in the synthesis of peptide and protein conjugates. The PEG chain provides water solubility and can improve the pharmacokinetics and bioavailability of drugs.
