Uses The quinone derivative, Menadione, can be formed by the oxidation of 2-methylnaphthalene and finds use as a synthetic form of vitamin K.
Astrochemistry According to NASA, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life. PAHs seem to have been formed shortly after the Big Bang, are abundant in the universe, and are associated with new stars and exoplanets.
Safety The LD50 for 2-methylnaphthalene is low, being 3850 mg/kg (rats).
