It is an orange solid that is only slightly soluble in water. It is stable in boiling water and dilute acids. Because of its possible toxicity, it is banned in the United States, although it is used in some European countries as an artificial sweetener. 1-n-Propoxy-2-amino-4-nitrobenzene 1-Propoxy-2-amino-4-nitrobenzene 2-Amino-4-nitro-1-n-propoxybenzene 5-Nitro-2-n-propoxyaniline 5-Nitro-2-propoxy-aniline 5-Nitro-2-propoxy-benzenamine 5-Nitro-2-propoxyaniline 5-Nitro-2-propoxybenzenamine Aniline, 5-nitro-2-propoxy- Aros x Aros-x Benzenamine, 5-nitro-2-propoxy- Benzenamine, 5-nitro-2-propoxy- (9CI) P 4000 P 4000 (Sweetener) Sweetening agent P 4000 Sweetening Agent P-4000 Ultrasuess Ultrasuss Ultrasweet C9H12N2O3 196.2032 196.08479226 5-nitro-2-propoxyaniline 5-nitro-2-propoxyaniline 553-79-7 CCCOC1=C(N)C=C(C=C1)N(=O)=O InChI=1S/C9H12N2O3/c1-2-5-14-9-4-3-7(11(12)13)6-8(9)10/h3-4,6H,2,5,10H2,1H3 RXQCEGOUSFBKPI-UHFFFAOYSA-N belongs to the class of organic compounds known as nitrophenyl ethers. These are aromatic compounds containing a nitrobenzene moiety that carries an ether group on the benzene ring.
