Cas no 20306-75-6 (N-Methylacetoacetamide, 70 wt% aqueous solution)
N-Methylacetoacetamide (MAA) is a versatile chemical intermediate, commonly supplied as a 70 wt% aqueous solution for ease of handling and storage. This formulation offers improved solubility and stability, making it suitable for various synthetic applications, particularly in pharmaceuticals and agrochemicals. The aqueous solution reduces flammability risks associated with pure forms while maintaining reactivity. MAA is widely used in the synthesis of heterocyclic compounds, active pharmaceutical ingredients (APIs), and specialty chemicals. Its high purity and consistent concentration ensure reliable performance in reactions such as condensations and cyclizations. The water-based delivery system also simplifies dosing and minimizes solvent waste, enhancing process efficiency.
