I. [Product Description]
Diketone-PEG11-Diketone (CAS 2353409-87-5) is a cross-linking agent based on an eleven-unit polyethylene glycol (PEG) modified with diketone functional groups, possessing dual functional characteristics of both organic intermediates and pharmaceutical intermediates. Its symmetrical diketone structure enables efficient molecular coupling, and the long-chain PEG imparts excellent water solubility and steric hindrance effects, which can significantly enhance product selectivity in catalytic reaction systems. This compound is particularly suitable for constructing functionalized nanocarriers and biocompatible materials.
