【General Description】

A clear colorless liquid. Flash point 158°F. Denser than water and slightly soluble in water. Vapors heavier than air.
【Reactivity Profile】

METHYL ACETOACETATE(105-45-3) is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides
【Air & Water Reactions】

Very slightly soluble in water.
【Health Hazard】

May be harmful by inhalation, ingestion, or skin absorption. Causes eye irritation. May cause skin irritation.
