Description

30-Methyl-2,5,8,11,14,17,20,23,26,29-Decaoxahentriacontane is a high-purity, synthetic polyethylene glycol (PEG) derivative with a precisely defined molecular structure. This compound is valued for its role as a versatile, non-ionic surfactant and phase-transfer catalyst in advanced chemical synthesis and formulation. It is essential for industries requiring precise control over solubility, surface activity, and molecular architecture, such as pharmaceuticals, specialty polymers, and advanced material science.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, PEGylated active pharmaceutical ingredients (APIs), and drug delivery systems to enhance solubility and bioavailability.
• Polymer & Material Science: Serves as a functional monomer or cross-linker for creating specialized polyethers, hydrogels, and non-ionic surfactants with tailored properties.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly in organic synthesis and fine chemical manufacturing.
• Surface Modification Agent: Applied to modify the surface properties of nanoparticles, pigments, and other materials to improve dispersion and stability.
• Chemical Research & Development: A key building block in R&D for creating novel compounds with specific chain lengths and terminal functionalities.
• Lubricant & Plasticizer Additive: Functions as a synthetic base or additive in high-performance lubricants and polymer plasticizers.
