Use

The main uses of methylnaphthalene are as a raw material for dyestuff dispersants and heat transfer oils, and as a solvent for agricultural chemical. It is used in insecticide manufacturing; manufacture of phthalic anhydride; solvent in organic synthesis; asphalt and naptha constituent. It is also used as a test substance for the determination of the cetane number of diesel fuels. Further, it is employed in the preparation of 1-methylnaphthalene-d10 using deuterium oxide, sodium deuteroxide.
