I. [Product Introduction]
VA-PEG-His is a multifunctional organic intermediate. Through the precise coupling of valeric acid (VA), polyethylene glycol (PEG), and histidine (His), it combines biocompatibility and chemical modifiability. It can be used as a pharmaceutical intermediate or catalyst carrier and is suitable for the synthesis and functional modification of polymer materials. Its modular structure supports customized design to meet the needs of complex molecular construction.
