Diethylene glycol monomethyl ether (high purity) is a clear, colorless solvent widely used in coatings, inks, and cleaning formulations for its excellent solvency and low volatility. It is also used as an anti-icing additive in jet and other hydrocarbon fuels, a solvent for wood stains, lacquers and textile dye pastes, and a component of brake fluids. It serves as a coupling agent, reducing viscosity while improving application properties. This chemical has a CAS number of 111-77-3, molecular formula CH3OCH2CH2OCH2CH2OH, and a molecular weight of 120.15. It should be stored at ambient conditions and handled with caution, as it carries a "Danger" signal word. Molekula supplies Diethylene glycol monomethyl ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
