2-methylnaphthalene

(meth″ĭl-naf′thă-lēn″) [ methyl + naphthalene]
C11H10, a polycylic aromatic hydrocarbon made from coal tar. It is used in the manufacture of detergents, insecticides, solvents, and vitamins. It has been found as a contaminant in rivers and other water sources and in some food packaging.
