Azido-PEG2-C2-acid features a terminal azide group paired with a carboxylic acid functionality across a short, hydrophilic PEG spacer. This bifunctional architecture enables efficient copper-free click conjugation while maintaining solubility and compatibility with biomolecular labeling workflows.
Azido-PEG2-C2-acid serves as a versatile bifunctional linker for bioconjugation and polymer chemistry, combining a reactive azide group with a carboxylic acid functionality separated by a two-atom ethylene glycol spacer. The PEG2 chain enhances solubility and reduces non-specific binding, while the terminal acid enables amide coupling under standard conditions. This reagent facilitates site-specific conjugation in peptide, antibody, and oligonucleotide modifications, offering reliable stability and ease of purification in aqueous and organic media.
