4-Methylpyridine Chemical Properties,Uses,Production

Chemical Properties

Clear light yellow liquid


ChEBI: A methylpyridine in which the methyl substituent is at position 4.


manufacture of isonicotinic acid and derivatives. In waterproofing agents for fabrics. As solvent for resins.

General Description

Colorless moderately volatile liquid.

Air & Water Reactions

Highly flammable.

Reactivity Profile

4-Methylpyridine 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.

Health Hazard

ACUTE/CHRONIC HAZARDS: Moderate fire risk.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
