Chemical Properties

Colourless to yellowish clear liquid

Uses

N-Methylacetoacetamide (min. 70% in water) (MMAA) is used as intermediate for the manufacture of insecticides, e.g. monocrotophos Product Data Sheet

Uses

N-Methylacetoacetamide is a starting material in the synthesis of 1-Carbamoyl-2-oxopropyl acetate with the aid (diacetoxyiodo)benzene (DIB) as the oxidant. Also, it is a reagent used in the synthesis of 10H-Phenothiazines, which possesses for their biological activity against the regulatory enzymes involved in inflammatory diseases.
