CAS 9004-76-6 — Tetraglycol

Tetraglycol, also called diethylene glycol monobutyl ether, is a solvent and coupling agent widely used in industrial coatings, inks, and cleaning formulations for its ability to dissolve a range of polar and nonpolar substances. It acts as a wetting agent, humectant, and plasticizer in formulations requiring moderate volatility and good solvency. This chemical has a CAS number of 9004-76-6, with no signal word classification under GHS, indicating low acute toxicity. It is a clear, colorless liquid with a mild odor, miscible with water and most organic solvents. Typical purity is ≥99% with minimal impurities like diethylene glycol or butanol. Molekula supplies Tetraglycol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
