Atrazine Triazines Herbicide

Common name: Atrazine

Chemical name:

2-Chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine; 2-chloro-4-ethylamino-6-isopropylamino-s-triazine; 

Molecular formula: C8H14ClN5

Structural formula:

Molecular weight: 215.68

CAS No. : 1912-24-9

Physical and chemical properties:

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

Usage：

Atrazine is a systemic selective pre-emergence and post-emergence herbicide. It is mainly absorbed by roots, but it is rarely absorbed by stems and leaves, and it is quickly transmitted to plant meristems and leaves, interfering with photosynthesis and causing weeds to die. In resistant crops such as corn, it is decomposed by corn ketolase to produce non-toxic substances, so it is safe for crops. Atrazine is highly water-soluble and has a greater mobility in the soil than simazine. It is easy to be washed by rain to a deeper layer, resulting in an inhibitory effect on some deep-rooting weeds. It can be decomposed by microorganisms in the soil and has a residual effect. Depending on the dosage, soil texture and other factors, it can last as long as half a year. It is suitable for controlling annual and biennial broad-leaved weeds and monocotyledonous weeds in corn, sorghum, woodland, grassland, sugarcane, etc.
