Azide-PEG3-Carboxylic acid is a bifunctional linker with terminal carboxyl and azido groups.

This molecule is hydrophilic and suitable for the synthesis of water-soluble conjugates.

The azide group can enter into [3+2]-dipolar cycloaddition reactions with biomolecules containing an alkyne moiety (Click Chemistry reactions), and the carboxyl group can be activated and react with various amines.

The repertoire of the synthesized bioconjugates can be very broad; for example, different antibody-drug conjugates (ADC) can be generated using this approach. Also, the conjugation of a PEG linker to a molecule can increase its stability and solubility in water, as well as reduce the immunogenicity.

Azide-PEG3-Carboxylic acid 是一种具有末端羧基和叠氮基的双功能接头。这种分子是亲水的，适合合成水溶性结合物。

合成的生物偶联物的库可以非常广泛； 例如，可以使用这种方法生成不同的抗体-药物偶联物 (ADC)。 此外，PEG 接头与分子的缀合可以增加其在水中的稳定性和溶解度，并降低免疫原性。

This compound is a PEG-linker with four monomer units (PEG4) with terminal hydroxy and amino groups for biomolecule conjugation.

Primary amines readily react with activated carboxyl groups, and the terminal hydroxyl group in the crosslinker can react with esters, azides, amines, and halogen derivatives in various conditions.

Polyethylene glycol linkers have low molecular weight, are non-toxic, and form conjugates with increased solubility. The field of use of these molecules is rather wide, varying from synthesis of new polymers to biomedicine.
