Che, Chao published the artcileStudies on Pyridine Derivatives. IX. Synthesis and Herbicidal Activities of N-(1-carbomethoxy)-ethyl-N-[5-(2-chloropyrid-4-yl)-1,3,4-thiodiazol-2-yl] Amides, COA of Formula: C6H4ClNO2, the publication is Nongyaoxue Xuebao (2004), 6(3), 15-20, database is CAplus.
In order to investigate the structure-activity relationship and improve the activity of herbicidal lead compound 2-sec-butylamino-5-(2-chloropyrid-4-yl)-1,3,4-thiodiazole (BCPT), which was found in previous work on pyridine derivatives, a novel series of N-(1-carbomethoxy) ethyl-N-[5-(2-chloropyrid-4-yl)-1,3,4-thiodiazol-2-yl] amides were synthesized and subjected to post-emergence herbicidal tests. All the compounds showed much weaker herbicidal activity than BCPT itself. The results suggested that BCPT might act to herbs in different way to amide herbicides.
Nongyaoxue Xuebao published new progress about 6313-54-8. 6313-54-8 belongs to chlorides-buliding-blocks, auxiliary class Pyridine,Chloride,Carboxylic acid, name is 2-Chloroisonicotinic acid, and the molecular formula is C6H4ClNO2, COA of Formula: C6H4ClNO2.
