Product Description -
PurePEG High Purity HO-PEG4-Benzyl Ester contains a hydroxy group and a benzyl protected carboxylic acid. The benzyl is easily removed under mild deprotection condition to afford a free acid that can be used to conjugate with an amine-bearing biopolymer, such as protein, oligonucleotide, etc. The hydroxy group can be derivatized to more reactive functional groups. The PEG spacer adds aqueous solubility to the newly formed complex. PurePEG's High Purity HO-PEG4-Benzyl Ester has an exact number of PEG units, with a specific chemical structure and precise molecular weight.
