6-Bromo-7-chloro-3H-imidazo[4 5-b]pyridine（CAS# 83472-62-2)

Introduction

3-Methyl-2,4-dichlorobenzoic acid is an organic compound. The following is an introduction to its nature, use, preparation method and safety information:

Quality:

- Appearance: Colorless crystalline solid

- Solubility: soluble in organic solvents such as ethanol, ether and methylene chloride, insoluble in water

Use:

- Pesticides: 3-methyl-2,4-dichlorobenzoic acid is a broad-spectrum herbicide that can be used to control the growth of a variety of weeds, such as the grass around crops such as kale, legumes, and corn.

Method:

3-Methyl-2,4-dichlorobenzoic acid can be prepared by chlorination of p-methylanise ether (3-methylanisole). The specific preparation method can involve the following steps:

Dissolve 3-methylanisole in anhydrous hydrochloric acid.

Sodium chlorite (NaClO) or potassium chlorite (KClO) were added as chlorine sources.

The reaction mixture is stirred at low temperatures, usually between 0-5 °C.

After the reaction is completed, the mixture is filtered or extracted to obtain a 3-methyl-2,4-dichlorobenzoic acid product.
