1-METHYLPYRENE Usage And Synthesis

Chemical Properties

Light yellow to light brown solid

Uses

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

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.
