A colorless crystalline, the vapor pressure 0.2μPa(20), the density of 1.543 (20 ° C). Solubility (20 ° C) : Water 0.51 grams / liter, dichloromethane 50-100 grams / liter,.Isopropanol 1-2 grams / liter, toluene 0.5-1 grams / liter, hexane <0.1 grams / liter.Stability: In normal storage conditions,in neuter and acidic medium is stable, in alkaline water medium environment will slow decompose.

Stir the toluene solution of N - (2 - chloro - 5 - methyl pyridine) ethyl diamines under room temperature, add hydrobromic acid, and obtain circular compounds. Then add concentrated sulfuric acid to the circular compounds under 0. Finally,add fuming nitric acid to reaction mixture and stir it for two hours under 0.  

Application to trees

When used on trees, it can take 30 – 60 days to reach the top, (depending on the size and height) and enter the leaves in high enough quantities to be effective. Imidacloprid can be found in the trunk, the branches, the twigs, the leaves, the leaflets, and the seeds. Many trees are wind pollinated. But others such as fruit trees, Linden, Catalpa, and Black Locust trees are bee and wind pollinated and imidacloprid would likely be found in the flowers in small quantities. Higher doses must be used to control boring insects than other types.
