Pharmaceutical intermediates. Methylcyclohexane is an important organic solvent and extractant, which can be used as a solvent for rubber, paint, varnish (some paint solvents also use methylcyclohexane), and can be used as oil extractant. Methylcyclohexane can be used in organic synthesis as solvent and analytical reagent. In addition, methylcyclohexane can also be used as a standard for thermometer calibration. The correction solution is usually made of methylcyclohexane as the main component.
