Propargyl-PEG2-CH2COOtBu is a PEGylation reagent that is commonly used in bioconjugation and drug delivery applications. PEGylation refers to the attachment of polyethylene glycol (PEG) chains to molecules, which can enhance their stability, solubility, and pharmacokinetic properties. Propargyl-PEG2-CH2COOtBu is a heterobifunctional PEG that contains an alkyne group (propargyl) at one end and a protected carboxylic acid group (t-butyl ester) at the other end. This unique structure allows for selective conjugation with molecules containing azide or amine groups through click chemistry or peptide coupling reactions, respectively. With its high purity and excellent stability, Propargyl-PEG2-CH2COOtBu is a reliable choice for researchers and pharmaceutical companies looking to develop PEG-modified products with precise control over the PEG linker length and functionality
