2243-57-4 - Introduction
2-Naphthylhydrazine is an organic compound with the chemical formula C10H9N2. It is a hydrazine structurally derived from naphthalene and is a white crystalline solid.
2-Naphthylhydrazine is mainly used as a reagent in organic synthesis. It can be used as a reagent for carbamate, for the Barnilam reaction and the derivatization of Lappa acid. In addition, it can also be used in the synthesis of organic dyes and pesticides.
The preparation method of 2-Naphthylhydrazine can be obtained by the reaction of 2-naphthylthionyl chloride and hydrazine after reduction. First, 2-naphthothionyl chloride is added to an organic solvent, and hydrazine suspension is immersed in the solvent to react. Subsequently, the reaction product is reduced by the addition of a reducing agent, such as sodium sulfite, to form 2-Naphthylhydrazine.
Regarding safety information, 2-Naphthylhydrazine is an organic compound, and attention should be paid to its safety during use and storage. It may cause irritation to the skin, eyes and respiratory tract, so it is necessary to wear appropriate personal protective equipment, such as laboratory gloves, goggles and protective masks. In addition, 2-Naphthylhydrazine is a potentially carcinogenic substance, so prolonged exposure and inhalation should be avoided.
When handling and disposing of 2-Naphthylhydrazine, it is necessary to follow local environmental regulations and take appropriate measures for storage and waste disposal. When using or handling 2-Naphthylhydrazine, follow safe operating procedures and pay attention to laboratory safety.
