Ald-Ph-PEG24-TFP ester is a long chain PEG TFP ester that is reactive with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The hydrophilic PEG chain increases the water solubility of compounds. Longer PEG chains have better water solubility properties relative to shorter PEG chains. Reagent grade, for research purpose.
