653-11-2 - Introduction

2,3,5, is an organic compound with the chemical formula C6H3F4N2. It is a colorless crystalline solid, soluble in some organic solvents such as methanol, acetonitrile and dichloromethane.

2,3,5, has a certain purpose. It can be used as an intermediate in the synthesis of organic fluorescent dyes and photosensitive materials. In addition, it can also be used in the preparation of photovoltaic devices and the preparation of organic optoelectronic devices.

The method for preparing 2,3,5, and phosphene is generally obtained by the reaction of phenylhydrazine and tetrafluoroacetophenone. First, phenylhydrazine and tetrafluoroacetophenone are heated to react in dichloromethane or alcohol solvent, and then crystallized and dried to obtain pure 2,3, 5,4.

Regarding safety information, 2,3,5, is a chemical, and attention should be paid to the safety of its use and storage. It may be irritating to the skin and eyes, so you should take appropriate protective measures when exposed, such as wearing protective gloves and goggles. In addition, when using should avoid inhalation of its dust or steam, so as not to cause damage to the respiratory system. When stored, it should be kept in a sealed container, away from fire and oxidizing agents.
