Description

3,6,9,12-Tetraoxatetradecan-1-Ol is a high-purity polyether glycol derivative, also known as Tetraethylene Glycol Monomethyl Ether. This versatile chemical intermediate is valued for its excellent solvating properties and ability to act as a non-reactive, high-boiling point solvent or a hydrophilic spacer in complex syntheses. It is essential for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking reliable, high-quality raw materials for formulation and process chemistry.

Application

• Pharmaceutical Intermediate: Used as a solvent or a building block in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems.
• Polymer & Resin Production: Serves as a monomer or chain extender in the manufacture of polyurethanes, polyesters, and other specialty polymers.
• Agrochemical Formulations: Employed as a co-solvent or penetrant in pesticides, herbicides, and other crop protection products.
• Chemical Synthesis: Acts as a phase-transfer catalyst or a high-boiling point reaction medium in organic synthesis.
• Inks & Coatings: Functions as a coalescing agent or flow modifier in specialty ink, paint, and coating formulations.
• Gas Treating & Purification: Utilized in formulations for gas dehydration and acid gas removal processes.
