I. [Product Introduction]
VA-PEG-CHO (Valeric Acid-Polyethylene Glycol-Aldehyde) is a multifunctional organic intermediate, possessing both biocompatibility and controllable reaction activity. Its PEG chain can optimize the hydrophilic-hydrophobic balance, and the aldehyde group provides an efficient directional coupling site. It is suitable for the construction of catalyst carriers and the synthesis of pharmaceutical intermediates, and is widely used in the field of functional modification of polymer materials.
