Definition
ChEBI: 1-Methylpyrene is a member of pyrenes.
General Description
Plates (in ethanol) or brown-green powder.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 1-METHYL PYRENE, 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. 1-METHYLPYRENE may be sensitive to prolonged exposure to light.
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition 1-METHYLPYRENE emits acrid smoke and fumes.
Fire Hazard
Flash point data for 1-METHYLPYRENE are not available. 1-METHYLPYRENE is probably combustible.
