2Methyl2nonanol

2-Methyl-2-nonanol is a branched-chain aliphatic alcohol with the chemical formula C10H22O. It belongs to the class of secondary alcohols, characterized by a hydroxyl group (-OH) attached to a secondary carbon atom. This compound features a nine-carbon chain with a methyl substituent at the second carbon position, giving it its distinct structural configuration.

The chemical is typically synthesized through the hydrogenation of corresponding ketones or via the aldol condensation of aldehydes and ketones, followed by reduction. It is often used as an intermediate in organic synthesis, particularly in the production of fragrances, flavorings, and pharmaceuticals. Due to its hydrophobic nature and mild odor, it may also serve as a solvent or additive in certain industrial applications.

2-Methyl-2-nonanol exhibits physical properties typical of medium-chain alcohols, including a clear, colorless liquid appearance at room temperature. Its boiling point is around 190–195°C, and it has limited solubility in water but dissolves well in organic solvents like ethanol and hexane. The compound is relatively stable under normal conditions but may undergo oxidation or polymerization under harsh conditions.

In terms of safety, 2-methyl-2-nonanol is generally considered low in toxicity, though proper handling precautions should still be observed due to its potential irritant effects on skin and eyes. It is not classified as highly hazardous but should be stored away from oxidizing agents and strong acids to prevent unwanted reactions.

Research into its applications continues, particularly in the development of specialty chemicals where its unique structural properties can be advantageous. As with many organic intermediates, its use is often tailored to specific industrial needs rather than broad commercial demand.
