Introduction

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

Quality:

- 3,4-Dichloronitrobenzene is a colorless crystal or light yellow crystal with a strong fumigation odor.

- Insoluble in water at room temperature, but soluble in most organic solvents.

Use:

- 3,4-Dichloronitrobenzene can be used as a chemical reagent such as a substrate for nitrosylation reactions.

- It can also be used as a precursor to the synthesis of other organic compounds, such as glyphosate, a herbicide.

Method:

- 3,4-Dichloronitrobenzene is usually prepared by chlorination of nitrobenzene. The specific preparation method can use a mixture of sodium nitrite and nitric acid, and react with benzene under appropriate reaction conditions. After the reaction, the target product is purified by crystallization and other steps.

Safety Information:

- 3,4-Dichloronitrobenzene is toxic and may cause harm to human health. Exposure, inhalation, or ingestion of this substance may cause eye, respiratory and skin irritation.

- This compound should be stored in a well-ventilated, dry, cool place, away from combustibles and oxidizing agents.
