3947 Nitrapyrin Nitrapyrin is an exogenous organic compound with the formula C6H3Cl4N and an average molecular weight of 230.91 g/mol. It exists as a solid at room temperature. Nitrapyrin belongs to the halopyridines, a subclass of pyridines and derivatives within the organic compounds. Used as an agricultural chemical, nitrapyrin inhibits nitrification in grain and reduces nitrogen losses from arable land. It inhibits or kills Nitrosomonas bacteria and is registered by the U.S. Environmental Protection Agency (EPA) as a nitrification inhibitor to slow and reduce the loss of nitrogen from soil when used in conjunction with urea and other ammoniacal fertilizers. The compound is found in or released from five recorded sources, including soap detergents in household cleaning and consumer products, ceilings in building and construction, and antennas, radio transmission systems, and television systems in electrical and electronic equipment. Nitrapyrin interacts with five recorded protein targets: Cytochrome P450 1A1 (CYP1A1), Cytochrome P450 2B6 (CYP2B6), Cytochrome P450 3A4 (CYP3A4), Nuclear receptor subfamily 1 group I member 2 (NR1I2), and one other protein. 1929-82-4 16004 C6H3Cl4N 230.9 White powder. No indication of carcinogenicity to humans (not listed by IARC). Nitrapyrin (trade name N-Serve) is used as an agricultural chemical. Nitrapyrin is currently registered by the U.S. Environmental Protection Agency (EPA) as a nitrification inhibitor to slow and reduce the loss of nitrogen from soil when used together with urea and other ammoniacal (ammonia containing) fertilizers. 2013-04-25T07:56:53Z 2026-08-23T09:06:02Z C18751 true ClC1=CC=CC(=N1)C(Cl)(Cl)Cl C6H3Cl4N InChI=1S/C6H3Cl4N/c7-5-3-1-2-4(11-5)6(8,9)10/h1-3H DCUJJWWUNKIJPH-UHFFFAOYSA-N 230.907 228.901959929 Exogenous Solid 3.4 CHEMBL1557091 15205 CHEM002853 DTXSID0024216 NS00005534 2-chloro-6-(trichloromethyl)pyridine 12.89 49.87330000000001 18.77793419039424 1 1 0 -0.9756251142198019 0 1 3.87 -3.37 9.95e-02 g/l Organic compounds Organoheterocyclic compounds Pyridines and derivatives Halopyridines 103 CED0013188 DCUJJWWUNKIJPH-UHFFFAOYSA-N 2000000000000000000000000000000000000000000000000001000000000000002000000000000000000000000000000000000000000000400100040000000000000020800000000000000000000000000000000000100000000000000000000000000000000000000000020000000000000001000000000000800000020000000000000000000000000000000000000000000000000000000000000000080000000000000000000000000000000000000000000000000000000000000000000000000010000000000000000202000000000000000000000001000040000000000000000000000000000020000000000000 100080000102020080800000008820000080040000040000002020420200000c5000003400800000000001000280000004200020008c20010000443000a0400084110c00020004001090100001620000000105904200003220000420000000000c22240600400220080000004010020020008030000980041188080200110002024000080c4000200800120008800008100c0012550014020000080000000080800300000000c00008000800002c221002c000008041084010000200004002100300008404000a060180000000010080000000004448400000000000080001020000001000010004000000100011200000100010004000020000000050000000 776t3gAAAAAQAAAAAwAAAAAAAAALAAAACwAAAIABEQAgAAAAAQZAKAAAAAME BkBoAAAAAwMBBkBoAAAAAwMBBkBoAAAAAwMBBkAoAAAAAwQHQCgAAAADAwYA IAAAAAQRACAAAAABEQAgAAAAAREAIAAAAAELAAEAAQJoDAIDaAwDBGgMBAVo DAUGaAwFBwAHCAAHCQAHCgAGAWgMQgEAAAAGAQYFBAMCFwQAAAAAAAAAFg== 2026-09-19T04:00:59Z
