In summary, the safety of Ximing 5-chloro-8- {[4-ethyl-5- (methylthio) -4H-1,2,4-triazole-3-yl] methoxy} quinoline must be investigated in depth from the aspects of chemistry, toxicology and environment before a more accurate conclusion can be obtained.

There are many quinoline-related derivatives of 5-chloro-8- {[4-ethyl-5- (methylthio) -4H-1,2,4-triazole-3-yl] methoxy} quinoline. Here is the style of ancient literature for you.
This compound has its derivation path, or it is in a complex state due to the change of the substituent. At the triazole ring, if the length of the alkyl group, the branch, or the structure of the thioether substituent is changed, other derivatives can be obtained. If the alkyl group of different chain lengths is 4-ethyl, and the methylthio group is substituted with different thioether structures, the new product and properties may change.
Furthermore, the quinoline ring is also an important place for derivation. At different check points, substituents such as hydroxyl, amino, and halogen atoms are introduced to obtain a series of new derivatives. And the positions and quantities of the substituents on the ring are different, and the activities and physical and chemical properties of the compounds are different.
In addition, if the methoxy group connecting the triazole ring and the quinoline ring is replaced by other connecting groups containing oxygen and nitrogen, new derivatives can also be created. These derivatives may have potential uses in the fields of medicine, pesticides, etc. The investigation of its pharmacological activity and biological activity still awaits the Fang family's in-depth study to clarify its properties and expand its uses, such as the ancients exploring treasures and finding treasures in unknown environments for later generations.
