Properties and stability

Avoid contact with strong acids, alkalis, and strong oxidants.Slightly irritating to the eyes, but not irritating to the skin. Animal experiments have shown no teratogenic or mutagenic effects

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from acids, alkalis, and oxidants, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.

Synthesis method

1. Chloroaniline can be prepared by the reaction of 3-chlorophenyl isocyanate and isopropyl alcohol. Or it can be obtained by the reaction between 3-chloroaniline and isopropyl chloroformate.

2.Chloraniline is prepared from the reaction of 3-chlorophenyl isocyanate and isopropyl alcohol. Or it is prepared from 3-chloroaniline and isopropyl chloroformate in the presence of sodium hydroxide.

3.It is both a plant growth Conditioners are also herbicides. It inhibits β-amylase activity, inhibits plant RNA and protein synthesis, interferes with oxidative phosphorylation and photosynthesis, and damages cell division, thus significantly inhibiting potato germination during storage. It can also be used for thinning flowers and fruits on fruit trees. At the same time, chlorpheniramine is a highly selective pre-emergence or early post-emergence herbicide. The herbicide is absorbed by the spores of grass weeds. It is mainly absorbed by the roots of the plant. It can also be absorbed by the leaves. It travels upward and downward in the body. Through conduction, it can effectively control annual grass weeds and some broadleaf grasses in wheat, corn, alfalfa, sunflower, potato, sugar beet, soybean, rice, beans, carrot, spinach, lettuce, onion, pepper and other crops.

Purpose

1. Used as a herbicide, mainly used to inhibit potato germination during storage.

2.Plant growth regulator and herbicide. It not only inhibits β-amylase activity, inhibits plant RNA and protein synthesis, interferes with oxidative phosphorylation and photosynthesis, and damages cell division. It is also a highly selective pre-emergence or early post-emergence herbicide. The herbicide is absorbed by the spores of grass weeds, mainly by the roots of the plant, and can also be absorbed by the leaves. It conducts upward and downward in the body and is effective. Control annual grass weeds and some broadleaf grasses on crops such as wheat, corn, alfalfa, sunflower, potato, sugar beet, rice, beans, carrots, spinach, lettuce, onions, and peppers. Use alone or mixed to control sensitive weeds. Depending on the soil organic matter and temperature, appropriately increasing the dosage can expand the grass killing spectrum.
