Atrazine

CAS：1912-24-9

Molecular formula：C8H14ClN5

Molecular weight：215.68

Structure：

Chemical property:

Atrazine is a colorless crystal with a melting point of 173 ~ 175 ℃. Soluble in water, methanol and chloroform. It is stable in neutral, slightly acidic and slightly alkaline media, but alkali and inorganic acids can hydrolyze it into hydroxyl derivatives without herbicidal activity at high temperature. It is prepared by reacting 2,4,6-trichloro-1,3,5-triazine with ethylamine and isopropylamine successively.

Purpose:

1.It is a special chemical herbicide for corn, sugarcane, sorghum and other places. It is used for weeding before and after bud of many crops.

2.Biochemical research. It is used for quality assurance and quality control in environmental monitoring, analysis and testing, as well as instrument calibration, method verification and technical arbitration.

Properties

Atrazine is a selective pre - and post seedling herbicide. It is mainly absorbed by roots, but little by stems and leaves. It is quickly transmitted to plant meristem and leaves, interfering with photosynthesis and killing weeds. In resistant crops, such as maize, it is decomposed by zeaxenase to produce non-toxic substances, so it is safe for crops. Atrazine has high water solubility, and its mobility in soil is greater than that of simazine. It is easy to be leached to deeper layer by rain, resulting in inhibition of some deep-rooted weeds. It can be decomposed by microorganisms in soil. The residual period can be as long as half a year depending on the dosage of Atrazine, soil texture and other factors. It is suitable for controlling annual and biennial broadleaf weeds and monocotyledon weeds in corn, sorghum, woodland, grassland and sugarcane.
