Nature:
-Appearance: 2, acid is a white crystalline solid.
-Solubility: It is less soluble in water and more soluble in organic solvents such as ethanol and acetone.
-Melting point: Its melting point is about 153-155 ° C.
-Stability: 2, acid is a stable compound.
Use:
-Chemical reagents: 2. acid can be used as Reagents for Organic Synthesis, for example, as an important intermediate in the construction of compound frameworks.
-Drug intermediates: It can also be used to manufacture drug intermediates, such as antiviral and anticancer drugs.
Method:
2. acid is usually synthesized by the following steps:
1. Using p-fluoronitrobenzene as starting material, the nitration reaction was carried out under acidic conditions to obtain 2,3-difluoro -4-nitrobenzene.
2. 2,3-difluoro -4-nitrobenzene is subjected to reduction reaction to obtain 2,3-difluoro -4-aminobenzene.
3. Finally, 2,3-difluoro-4-aminobenzene is hydroxylated to obtain 2, acid.
Safety Information:
- 2, acid is a stable and relatively safe compound under standard temperature and pressure.
-Avoid contact with strong oxidants during handling and storage to prevent dangerous reactions.
-Wear appropriate personal protective equipment, such as laboratory gloves and goggles, to avoid direct contact with skin and eyes.
-During the operation, care should be taken to avoid inhaling the vapor of its powder or solution, because it may have a stimulating effect on the respiratory tract and mucous membranes.
-In the event of accidental ingestion or inhalation of large quantities, seek immediate medical attention.
Please note that when conducting any chemical experiments or using organic compounds, you should follow laboratory safety procedures and ensure safety in accordance with relevant regulations and guidelines.
