Hexyl methyl ether (CAS 4747-07-3) is a clear, colorless liquid with the molecular formula C?H??O. It is an aliphatic ether characterized by its low viscosity and moderate volatility, making it suitable as a solvent in organic synthesis and industrial applications. The compound exhibits good stability under standard conditions and is miscible with many organic solvents while being sparingly soluble in water. Its balanced polarity and relatively high boiling point (≈126°C) enable use in reactions requiring mild heating. Hexyl methyl ether is often preferred for its low toxicity compared to shorter-chain ethers, reducing handling risks. Typical applications include extraction processes, fuel additives, and specialty chemical formulations.
