Ald-Ph-PEG4-acid is a small molecule PEG reagent. The benzaldehyde group is reactive with hydrazide and aminooxy moiety. The terminal carboxylic acid can couple with primary amines in the presence of activators such as EDC or HATU to form a stable amide bond. The hydrophilic PEG linker increases the solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
