General Description

Yellow liquid or oil.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

8-Methylquinoline may be sensitive to exposure to light. May react vigorously with strong oxidizing agents and strong acids . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

8-Methylquinoline is combustible.
