Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2,3,5-Trichloropyridin-4-ol, is researched, Molecular C5H2Cl3NO, CAS is 1970-40-7, about Effect of soil types on the performance of some total growth control chemicals.Synthetic Route of C5H2Cl3NO.
Bromacil, m-(3,3-dimethylureido)phenyl tert-butylcarbamate (Nia 11092), atrazine, prometone, and 2-(sec-butylamino)-4-(ethylamino)-6-methoxy-s-triazine (14254) were most effective in heavy (clay) soils while pyriclor and diuron were more effective in sandy loam soils.
