2-Methylnaphthalene is a simple polycyclic aromatic hydrocarbon (PAH). It is generally isolated from coal tar, of which it is a minor component.[2]
Uses
The quinone derivative, Menadione, can be formed by the oxidation of 2-methylnaphthalene and finds use as a synthetic form of vitamin K.[3]
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.[4] PAHs seem to have been formed shortly after the Big Bang, are abundant in the universe,[5][6][7] and are associated with new stars and exoplanets.[4]
