5-Nitro-2-propoxyaniline

5-Nitro-2-propoxyaniline, also known as P-4000 and Ultrasüss, is one of the strongest sweet-tasting substances known, about 4,000 times the intensity of sucrose (hence its alternate name, P-4000). It is an orange solid that is only slightly soluble in water. It is stable in boiling water and dilute acids. 5-Nitro-2-propoxyaniline was once used as an artificial sweetener but has been banned in the United States because of its possible toxicity.
