I. [Product Description]
NH2-PEG-VA (Amino-polyethylene glycol-valeric acid) is a multifunctional organic intermediate that combines the high reactivity of amino groups with the excellent water solubility and biocompatibility of PEG segments. It is widely used in fields such as coupling reactions, carrier construction, and surface modification. The valeric acid group in its molecular structure can be further derivatized, making it suitable for catalytic systems or complex molecular assembly. It is a key component in the research and development of pharmaceutical intermediates and functional materials.
