3-氨基-5,6-二氯吡嗪-2-羧酸甲酯 - Introduction

methyl 3-amino-5, also known as methyl dichloramine acid (Mefenpyr-diethyl), is a heterocyclic compound with the chemical formula c14h15cl2n2.

Nature:
1. Appearance: colorless crystalline solid.
2. Melting Point: about 142-147 degrees Celsius.
3. Solubility: soluble in organic solvents such as methanol, ethanol and dichloromethane, insoluble in water.

Use:
Methyl dichloramine acid is a broad-spectrum glyphosate herbicide that can be used to control perennial herbaceous weeds and some herbaceous wild plants. It has good herbicidal effect on grass weeds in crops such as cereal crops, vegetables, cotton and fruit trees.

Method:
Methyl dichloramine acid is usually obtained by chemical synthesis. The specific preparation method can be by reacting 3-amino -5,6-dichloro -2-pyrazine with methyl butyl ether (MTBE), the target product is then purified by a series of chemical reactions and crystallization.

Safety Information:
1. Methyl dichloramine acid has certain toxicity to human health, so pay attention to protective measures when using it, avoid contact with skin and inhalation into the respiratory tract. Wear appropriate respiratory protective equipment and protective clothing when used.
2. Avoid contact with the eyes, such as Splash, should immediately rinse the eyes with plenty of water.
