I. [Product Description] 
Collagen-PEG-CHO (Aldehyde) is a multifunctional bioconjugation reagent. It achieves precise molecular modification through the high reactivity of the aldehyde group, combining the biocompatibility of collagen with the steric hindrance effect of PEG. As a high-performance organic intermediate, this product is suitable for the preparation of pharmaceutical intermediates and the directional coupling reaction in polymer material synthesis. Its controllable molecular weight distribution provides a flexible solution for catalyst design and functional modification.
