 2-Methylphenanthrene ,its Cas Register Number is 2531-84-2.The chemical synonyms of 2-Methylphenanthrene (CAS No.2531-84-2) are 2-Methyl-phenanthren ; 2-Methylphenanthrene ; Phenanthrene .The molecular structure of 2-Methylphenanthrene (CAS No.2531-84-2) is .

Mutation data reported. When heated to decomposition it emits acrid smoke and irritating vapors.

  2-Methylphenanthrene  (CAS No.2531-84-2) vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 2-METHYLPHENANTHRENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction. It may be sensitive to prolonged exposure to light.
