CAS 544-01-4 — Diisoamyl ether (mixture of isomers)

Diisoamyl ether is a synthetic ether composed of branched-chain amyl alcohol isomers, primarily used as a solvent in industrial applications, including coatings, inks, and adhesives. It serves as a non-polar, moderately volatile solvent that aids in dissolving resins and oils while minimizing odor and toxicity compared to alternatives like hexane. This mixture is classified as non-hazardous under standard handling conditions, with no signal word required on safety data sheets. Diisoamyl ether (CAS 544-01-4) appears as a clear, colorless liquid with a mild odor, boiling range of 115–135°C, and flash point above 23°C. It is miscible with most organic solvents but immiscible with water. Typical industrial grades offer purity above 98%, with trace impurities dependent on synthesis method. Molekula supplies Diisoamyl ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
