I. [Product Description]
VA-PEG-HZ is a multifunctional organic intermediate constructed by valeric acid, polyethylene glycol (PEG), and hydrazide groups through precise coupling technology. It combines excellent water solubility and reactivity. The PEG chain in its structure can significantly improve molecular compatibility, and the hydrazide group can serve as a highly efficient catalyst or coupling site, which is widely used in the fields of biomaterial modification and functional molecule synthesis.
