85118-02-1 - Introduction
2,4-difluorobenzamide is an organic compound with the chemical formula C7H5F2NO.
Nature:
-Appearance: 2,4-difluorobenzamide is a white crystalline solid.
-Solubility: It can be dissolved in polar organic solvents, such as ethanol and dimethylformamide.
-Melting point: The melting point of 2,4-difluorobenzamide is about 92-94°C.
-Stability: It is relatively stable at room temperature.
Use:
-Pesticide synthesis: 2,4-difluorobenzamide can be used as a synthetic intermediate for pesticides, such as for the synthesis of fungicides and herbicides.
-Medicinal chemistry: It can also be used to synthesize biologically active compounds and has application potential in drug research and development.
Preparation Method:
- 2,4-difluorobenzamide is generally obtained from fluorinated benzamide. First, one or more hydrogen atoms of benzamide are replaced by fluorine atoms by acting on benzamide by fluorine gas and hydrofluoric acid to give 2,4-difluorobenzamide.
Safety Information:
-The specific toxicity data of 2,4-difluorobenzamide are very limited, so caution is required when using it.
-When using or handling, take appropriate personal protective measures, such as wearing protective gloves and goggles, and avoid direct contact with skin and eyes.
-When storing, it should be stored in a dry, low-temperature, well-ventilated place, and away from fire and oxidizing agents.
-When mixed with other chemicals, be aware of possible reactions and potential hazards.
