What is 4-Methylcyclohexanemethanol?

Plain description, key identifiers and synonyms

4-methylcyclohexanemethanol is an alicyclic primary alcohol that is cyclohexane substituted by a hydroxy methyl group and methyl group at positions 1 and 4. It acts as a hydrotrope, solubilizing hydrophobic substances in aqueous environments. It also prevents protein aggregation, alters membrane dynamics and metal homeostasis, and is used in a flotation process for cleaning and processing coal. It is a primary alcohol, an aliphatic alcohol and a carbocyclic compound.
