Description

3,6,9,12,15,18,21,24,27,30,33,36,39,42,45-Pentadecaoxaheptatetracontane-1,47-Diol is a high-purity polyethylene glycol (PEG) derivative, specifically a long-chain PEG diol, known for its exceptional hydrophilicity and biocompatibility. This compound is a critical building block for creating advanced, water-soluble polymers and functional materials with precise molecular architectures. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and specialty chemical sectors who require reliable, high-quality PEGylation reagents and polymer precursors.

Application

• Pharmaceutical PEGylation: A key linker or spacer arm for conjugating therapeutic proteins, peptides, and oligonucleotides to improve solubility, stability, and circulation half-life.
• Bioconjugation Chemistry: Serves as a hydrophilic spacer in the synthesis of diagnostic reagents, antibody-drug conjugates (ADCs), and biosensors.
• Polymer Synthesis: A macro-initiator or monomer for producing block copolymers, hydrogels, and non-ionic surfactants with tailored properties.
• Surface Modification: Used to create anti-fouling, protein-resistant coatings on medical devices, nanoparticles, and chromatographic media.
• Drug Delivery Systems: Incorporated into the matrix of micelles, liposomes, and dendrimers to enhance biocompatibility and targeted delivery.
• Cosmetic & Personal Care: Functions as a humectant and conditioning agent in high-performance skincare formulations.
• Lubricants & Functional Fluids: Employed as a base or additive in specialty lubricants and heat transfer fluids.
