Application

Methylcyclohexane may be used as a solvent for the synthesis of unsolvated n-butylmagnesium chloride by the reaction of 1-chlorobutane with magnesium powder. It may also be used as the starting material to synthesize 1-methylcyclohexanecarboxylic acid.

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.
