3860 Carfentrazone-ethyl Carfentrazone-ethyl (C15H14Cl2F3N3O3) is an exogenous organic compound with an average molecular weight of 412.19 g/mol. It exists as a solid at room temperature. Carfentrazone-ethyl belongs to the triazoles, a subclass of azoles within the organic compounds. Used industrially as a biocide, this compound is a contact herbicide employed to control sedge and broadleaf weeds in cereals. It functions as a non-selective agent capable of complete vegetation control, as well as serving as a defoliant and desiccant in certain crops. Its mode of action involves the inhibition of protoporphyrinogen oxidase, which disrupts membranes and leads to cell death. The compound has been recorded in drinking water and water supply, as well as in building and construction floors. The recorded route of exposure is oral. Carfentrazone-ethyl interacts with six protein targets, including Interleukin-1 alpha (IL1A), Cytochrome P450 2B6 (CYP2B6), Cytochrome P450 2C19 (CYP2C19), and Cytochrome P450 2C9 (CYP2C9), along with two other proteins. 128639-02-1 86222 C15H14Cl2F3N3O3 412.2 White powder. LD50 (rat, oral) >5000 mg/kg LD50 (rat, dermal) >4000 mg/kg LC50 (rat, inhalation) >5.09 mg/L No indication of carcinogenicity to humans (not listed by IARC). This is a man-made compound that is used as a pesticide. Carfentrazone-ethyl is not considered to cause significant toxicity in helathy humans. But in patient with very large acute exposures or long-term chronic exposures, carfentrazone-ethyl may cause variegate porphyria or transient porphyria cutanea tarda-like syndrome. (L2125) Remove contaminated clothing and wash skin with soap and water. For eye exposure, copious irrigation with water or saline is used. The treatment is usually symptomatic and supportive. 2013-04-25T07:56:50Z 2026-08-19T09:40:23Z C11094 true CCOC(=O)C(Cl)CC1=CC(N2N=C(C)N(C(F)F)C2=O)=C(F)C=C1Cl C15H14Cl2F3N3O3 InChI=1S/C15H14Cl2F3N3O3/c1-3-26-13(24)10(17)4-8-5-12(11(18)6-9(8)16)23-15(25)22(14(19)20)7(2)21-23/h5-6,10,14H,3-4H2,1-2H3 MLKCGVHIFJBRCD-UHFFFAOYSA-N 412.191 411.036431358 Exogenous Solid CHEMBL2145069 77773 CHEM002766 DTXSID4032532 NS00019702 ethyl 2-chloro-3-[2-chloro-5-[4-(difluoromethyl)-3-methyl-5-oxo-1,2,4-triazol-1-yl]-4-fluorophenyl]propanoate 62.21 87.73620000000003 35.54515651596199 7 3 0 -7.254398304441514 0 2 3.99 -5.12 3.13e-03 g/l Organic compounds Organoheterocyclic compounds Azoles Triazoles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 776t3gAAAAAQAAAAAwAAAAAAAAAaAAAAGwAAAIABBgBgAAAAAQMGAGAAAAAC AggAKAAAAAMCBgAoAAAAAwQIACgAAAADAgYAYAAAAAMBEQAgAAAAAQYAYAAA AAICBkAoAAAAAwQGQGgAAAADAwEGQCgAAAADBAdAKAAAAAMDB0AoAAAAAwMG QCgAAAADBAYAYAAAAAEDB0AoAAAAAwMGAGAAAAADAQkAIAAAAAEJACAAAAAB BkAoAAAAAwQIACgAAAADAgZAKAAAAAMECQAgAAAAAQZAaAAAAAMDAQZAKAAA AAMEEQAgAAAAAQsAAQABAgACAyADBCgCAwUABQYABQcABwgACAloDAkKaAwK CyALDGgMDA1oDA0OAA0PaAwPEAAQEQAQEgAPE2gMExQoAgoVaAwVFgAVF2gM FxhoDBgZABgIaAwTC2gMQgIAAAAGCBgXFQoJBQwLEw8NFwQAAAAAAAAAFg== 2026-09-19T04:00:56Z
