[2,4-dichloro-6-(trifluoromethyl)phenyl]hydrazine - Introduction

4-amino -2, 2-difluoro-1, 3-benzodioxene (abbreviated as ADF) is an organic compound with the chemical formula C12H6F2N2. ADF is a yellow crystalline solid with a high melting and boiling point. Its solubility is poor, insoluble in water but soluble in most organic solvents.

ADF has many important applications. First, ADF is an important dye intermediate, which can be used to synthesize various organic dyes. Secondly, ADF can also be used as a fluorescent marker, which is widely used in biomedical and optoelectronic fields. In addition, ADF can also be used as a catalyst and a reducing agent in organic synthesis reactions.

There are two main methods of preparing ADF. One is obtained by reacting p-phenylenediamine with 2,2-difluoroacetyl chloride through a fluorination reaction. The other is obtained by reacting 4-amino -1, 3-benzodioxane with a fluorinating reagent such as hydrogen fluoride hydrofluoric acid. The process of preparing ADF needs to be carried out under inert gas, taking care to prevent the intermediate from being exposed to air and moisture.

Regarding the safety information of ADF, it is a low-toxic compound, but it is still necessary to pay attention to safe operation. Wear protective gloves and glasses when exposed to ADF to prevent the compound from causing irritation to the skin and eyes. Good ventilation should be maintained during operation to avoid inhalation of dust and vapor. When storing ADF, keep it in a sealed container away from fire and oxidizing agents.

In summary, 4-amino -2, 2-difluoro-1, 3-benzodioxene is an organic compound with a variety of applications such as dye intermediates, fluorescent markers, and catalysts. Its preparation method mainly has two kinds of fluorination reaction and reaction with fluorination reagent. Pay attention to safety during operation and storage, avoid contact with skin and glasses, and maintain good ventilation conditions.
