N,N-Dimethylacetoacetamide

CAS: 2044-64-6

Overview

N,N-Dimethylacetoacetamide ( CAS 2044-64-6 ), commonly abbreviated as DMAA, is a beta-ketoamide building block used across pharmaceutical synthesis, agrochemical development, and polymer chemistry.

It functions as a reactive intermediate and monomer component, enabling the construction of more complex molecular architectures in both fine chemical and industrial contexts.

In pharmaceutical manufacturing, DMAA serves as a key intermediate in the synthesis of active pharmaceutical ingredients, particularly where a beta-ketoamide motif is required for cyclization reactions.

Agrochemical producers use it in the preparation of herbicide and pesticide intermediates, where its reactivity toward nitrogen and carbon nucleophiles enables efficient route design.

In polymer chemistry, it acts as a functional monomer or co-monomer to introduce reactive ketone groups into polymer backbones, influencing crosslinking behavior and adhesion properties.

Specialty resin formulators also incorporate it where controlled reactivity during polymerization is a process requirement. DMAA is supplied as a liquid at standard commercial purity levels.

Material is typically 97% or higher for synthesis-grade material. Technical and reagent grades are the most commonly available specifications in the market for industrial procurement.

It is generally packaged in drums or intermediate bulk containers suited to industrial volumes. This ensures safe handling and transport for large-scale chemical manufacturing operations.
