Crotonaldehyde, stabilized appears as a clear colorless to straw colored liquid with a penetrating pungent odor. Flash point 55°F. Density 7.1 lb / gal. Very toxic by inhalation. May polymerize with the release of heat under exposure to heat or contamination. If polymerization takes place inside a container, the container may rupture violently. Less dense than water. Vapors heavier than air.

The warehouse is ventilated, low temperature and dry; stored separately from oxidants and acids

Explosive when mixed with air

Stability Air sensitive. Highly flammable. Readily forms explosive mixtures with air. May polymerize in the presence of acids, alkalies or amines. Uncontrolled polymerisation may lead to a rapid temperature rise. Incompatible with acids, bases, amines, strong oxidizing agents, butadiene, ketones, oxygen. May contain a stabilizer.
