Propargyl-PEG3-Acid(CAT: I014602) is a functionalized polyethylene glycol derivative commonly used in chemical biology, materials science, and drug delivery research. It features a propargyl group, enabling copper-catalyzed azide-alkyne cycloaddition (CuAAC, or “click chemistry”), and a terminal carboxylic acid group for further chemical modification or conjugation. The PEG3 spacer provides enhanced solubility, flexibility, and reduced steric hindrance, making it ideal for creating multifunctional biomolecules, nanocarriers, or surface modifications. Propargyl-PEG3-Acid is a highly reliable and versatile reagent, supporting a wide range of applications, including bio-orthogonal labeling, targeted delivery systems, and advanced material design. Its high purity ensures reproducibility and precision in experimental outcomes.
