So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Weber, Jerry B.; Best, J. A. researched the compound: 2,3,5-Trichloropyridin-4-ol( cas:1970-40-7 ).COA of Formula: C5H2Cl3NO.They published the article 《Activity and movement of 13 soil-applied herbicides as influenced by soil reaction》 about this compound( cas:1970-40-7 ) in Proceedings, Southern Weed Science Society. Keywords: herbicide soil acidity mobility; persistence herbicide soil. We’ll tell you more about this compound (cas:1970-40-7).
Broadleaf weeds were more prevalent in neutral soil (pH 7), than they were on acid soil (pH 5). The inverse was true for grass. The activities of 13 herbicides against broadleaf weeds on neutral soil were in the decreasing order: Dicamba [1918-00-9], bromacil [314-40-9], pyriclor [1970-40-7], NC 4780 [13577-71-4], fenuron [101-42-8], dichlobenil [1194-65-6], fluometuron [2164-17-2], prometryne [7287-19-6], chloramben [133-90-4], propachlor [1918-16-7], CDAA [93-71-0], chlorpropham [101-21-3], and paraquat [4685-14-7]. For grass, the activity was in the decreasing order: bromacil, pyriclor, NC 4780, dicamba, chloramben, fenuron, propachlor, fluometuron, CDAA, prometryne, chlorpropham, dichlobenil, and paraquat. Only prometryne and paraquat were soil pH-dependent, both compounds being more active on neutral soil than on acid ones. The relative mobilities of the herbicides were measured by their movements over the soil surface into adjacent control areas. Bromacil, pyriclor and NC 4780 were very mobile; fenuron, dichlobenil, propachlor, dicamba, chloramben, and fluometuron were of intermediate mobility; and chlorpropham, prometryne, CDAA and paraquat were immobile. The most persistent herbicides were bromacil, pyriclor, and NC 4780.
This compound(2,3,5-Trichloropyridin-4-ol)COA of Formula: C5H2Cl3NO was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
