Aldehyde PEG (Ald-PEG or CHO-PEG) is an amine-reactive PEG derivative used for site-specific modification of proteins, peptides, and biomaterials. The aldehyde group reacts with primary amines to form stable covalent bonds, making it ideal for protein PEGylation, hydrogel formation, and bioconjugate synthesis.

We offer high-quality Aldehyde PEG derivatives from grams to 100 kg GMP-grade supply, ensuring consistent quality, superior purity, and strong technical support to accelerate your bioconjugation and biomaterial research.
