Description

Azido-PEG1-CH2CO2H features a reactive azide group linked to a single ethylene glycol unit, terminating in a carboxylic acid. This bifunctional scaffold enables site-specific conjugation via click chemistry and facilitates purification or immobilization through the acidic moiety. Designed for bioconjugation workflows requiring short spacer length and high solubility.

Application

Azido-PEG1-CH₂CO₂H serves as a versatile bifunctional building block for bioconjugation and peptide synthesis, combining the reactivity of an azide group with the solubility and stability of a short PEG spacer. The carboxylic acid functionality enables direct coupling to amines via standard amide bond formation, while the terminal azide facilitates efficient copper-catalyzed or strain-promoted cycloaddition reactions. Ideal for modular construction of functionalized peptides, probes, and conjugates, it offers excellent bench stability and compatibility with common purification methods.
