Air and Water Reactions:No rapid reaction with air. No rapid reaction with water.
Reactive Group:Amines, Phosphines, and Pyridines
Reactivity Profile:7-Diethylamino-4-methylcoumarin is a lactone (behaves as an ester) and an amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
