Description

3,6,9,12-Tetraoxahexadecan-1-Ol CAS NO 1559-34-8 is a high-purity polyether glycol, specifically a tetraethylene glycol monoalkyl ether, valued for its excellent solvency and coupling properties. This compound is a crucial intermediate and functional additive in advanced formulations requiring precise control over hydrophilicity and surface activity. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for synthesis, purification, and as a non-ionic surfactant component.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, drug conjugates, and as a solubilizing agent in injectable formulations.
• Polymer & Resin Modification: Acts as a plasticizer, viscosity modifier, and chain extender in polyurethane, epoxy, and polyester systems.
• Agrochemical Formulations: Serves as a penetrant, emulsifier, and solvent in herbicides, pesticides, and plant growth regulators.
• Chemical Synthesis: Employed as a phase-transfer catalyst and reaction medium in organic synthesis, particularly for Williamson ether synthesis.
• Electronics & Cleaning: Used in precision cleaning solutions for semiconductors and as a component in photoresist developers.
• Cosmetics & Personal Care: Functions as a humectant and coupling agent in lotions, creams, and other topical products.
