Toxicology

N,N-Dimethylacetoacetamide (DMAAm) is a β-dicarbonyl compound that is utilized as a co-promoter in the production of unsaturated polyester resins used in coating materials and as an industrial intermediate in insecticide synthesis. Patents have also been issued for its use in hair colorants. However, DMAAm had limited toxicology and information available. DMAAm appears to have low toxicity in rodents. Smyth et al. reported an oral LD50 in male CarworthWistar rats of 22.6mL/kg (estimated to be approximately 19.8g/kg) and a dermal LD50 in male New Zealand rabbits of 14.1mL/kg (12.4g/kg) (single 8-h exposure). Oral gavage administration of DMAAm did not result in any mortality in rats (strain and gender not reported) at doses up to 3.2g/kg. DMAAm has been identified as a hydrolytic product and a degradation product of the insecticide dicrotophos ((dimethoxyphosphinyloxy)-N, N-dimethylcis-crotonamide) in soil, but was not found as a urinary metabolite of this insecticide in rats[1].
