1-METHYLPYRENE C??? ??, ??, ??

??? ??

Light yellow to light brown solid

??

1-Methylpyrene is a fluorescent probe useful for micellar aggregation number.

?? ??

Plates (in ethanol) or brown-green powder.

??? ?? ??

Insoluble in water.

?? ???

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.

????

ACUTE/CHRONIC HAZARDS: When heated to decomposition 1-METHYLPYRENE emits acrid smoke and fumes.

????

Flash point data for 1-METHYLPYRENE are not available. 1-METHYLPYRENE is probably combustible.
