2-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH).

On February 22, 2014, NASA announced a greatly upgraded database [1] [2] for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life. [1] PAHs seem to have been formed shortly after the Big Bang, are abundant in the universe, [3] [4] [5] and are associated with new stars and exoplanets. [1]

Several enzymes biodegrade 2-methyhlnaphthalene in anaerobic conditions. [6] [7]
