4584 Propyzamide Propyzamide is a solid compound with the formula C12H11Cl2NO and an average molecular weight of 256.13 g/mol. Propyzamide belongs to the benzoic acids and derivatives, a subclass of benzene and substituted derivatives within the organic compounds. This exogenous substance is used industrially as a biocide, herbicide (PMC10058801, PMC12882113), and pesticide (PMC11407745), as well as a degradant or impurity (PMC10058801, PMC12882113). The compound is present in polypropylene and has been recorded in six sources: building and construction materials such as floors and fencing, drinking water and water supply, radio transmission systems within electrical and electronic equipment, cigar cigarettes in household cleaning and consumer products, and molasses and the treatment of molasses in food processing. The recorded route of exposure is oral. Propyzamide interacts with ten recorded protein targets, including the urokinase plasminogen activator surface receptor (PLAUR), collagen alpha-1(III) chain (COL3A1), ATP-dependent translocase ABCB1, and the broad substrate specificity ATP-binding cassette transporter ABCG2, among six other proteins. 23950-58-5 32154 C12H11Cl2NO 256.12 White powder. LD50 (oral, male rat) = 8350 mg/kg bw LD50 (oral, female rat) = 5620 mg/kg bw LD50 (oral, male rat) = 8350 mg/kg bw LD50 (oral, female rat) = 5620 mg/kg bw No indication of carcinogenicity to humans (not listed by IARC). This is a man-made compound that is used as a pesticide. Propyzamide is pratically non-toxic to mammals on an acute oral exposure basis., however a 2-generation reproduction study in rats found that propyzamide caused effects on both adult and offspring body size. Propyzamide causes local irritation when applied to the skin. 2014-08-29T06:51:45Z 2026-08-18T15:53:03Z C14333 true CC(C)(NC(=O)C1=CC(Cl)=CC(Cl)=C1)C#C C12H11Cl2NO InChI=1S/C12H11Cl2NO/c1-4-12(2,3)15-11(16)8-5-9(13)7-10(14)6-8/h1,5-7H,2-3H3,(H,15,16) PHNUZKMIPFFYSO-UHFFFAOYSA-N 256.128 255.021769393 Exogenous Solid CHEMBL283487 29822 CHEM003490 DTXSID2020420 NS00000560 3,5-dichloro-N-(2-methylbut-3-yn-2-yl)benzamide 29.1 66.2799 25.476751401615406 2 1 1 14.20743055120656 -1.3343074927102117 0 1 3.24 -4.45 9.00e-03 g/l Organic compounds Benzenoids Benzene and substituted derivatives Benzoic acids and derivatives 572 CED0010556 PHNUZKMIPFFYSO-UHFFFAOYSA-N 20000000000000000000000000800000000000000000000000000000000020000000008000000000000000000000020000000000000000024800000000000000000000200000a0000000000000000000000000000000010000000000000000101000000010000000000000020000000000000000000040000000000000004000000080000000000000000000100000000000000000000000000000000000084000000000000000000000000000000000000000000010000000000000000000000000000010000000000000001000000000000000000000000000200040000000000400000000000000000000000000400000 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 ï¾­Þ������������������������€���`������� ������`�������h��������(�������(������@(������@h�������@(������� �����@h�������@(������� �����@h��������(�������h������������������ ��(��� ��h���h�� �� h� �h����� h�������� �h�B������ � ������������ 2026-09-19T04:01:20Z
