Description

n-Benzyl-n-Bis(Peg1-Oh) CAS NO 119580-47-1 is a specialized polyethylene glycol (PEG) derivative featuring a benzyl group and terminal hydroxyl functionalities. This bifunctional structure makes it a valuable intermediate for introducing hydrophilic PEG spacers and reactive sites into target molecules. It is primarily sought after by researchers and formulators in the pharmaceutical and specialty chemical industries for applications in drug delivery, bioconjugation, and polymer synthesis where controlled hydrophilicity and functionalization are critical.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs and as a linker for antibody-drug conjugates (ADCs) to improve solubility and pharmacokinetics.
• Polymer Chemistry: Serves as a monomer or chain extender for creating functionalized polyethers and block copolymers with tailored properties.
• Surface Modification: Employed to PEGylate surfaces, nanoparticles, or biomaterials to enhance biocompatibility and reduce non-specific binding.
• Crosslinking Agent: Utilized in the preparation of hydrogels and polymer networks due to its reactive hydroxyl end groups.
• Ligand and Catalyst Design: Acts as a scaffold or solubilizing group in the development of homogeneous catalysts and specialized ligands.
• Cosmetic and Personal Care Formulations: Functions as a humectant and conditioning agent in advanced skincare and haircare products.
