2-Amino-3,4,5,6-tetrafluorobenzoic acid,3,4,5,6-Tetrafluoroanthranilic acid - Introduction
2-amino-3,4,5,6-tetrafluorobenzoic acid is an organic compound with the molecular formula C7H4F4NO2. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
2-amino-3,4,5,6-tetrafluorobenzoic acid is a white crystalline solid, soluble in polar solvents such as methanol or ethanol, and insoluble in non-polar solvents such as carbon disulfide. It is stable at room temperature, but decomposes at high temperatures.
Use:
2-amino-3,4,5,6-tetrafluorobenzoic acid is commonly used as an intermediate for the synthesis of other organic compounds, such as pesticides and pharmaceuticals. It can also be used in areas such as dyes, paints and plastics.
Method:
2-amino-3,4,5,6-tetrafluorobenzoic acid can be prepared by ammonolysis of trifluorochloromethane and cyanoacetic acid. The specific step is to first react trifluoromethane and cyanoacetic acid to produce 2-amino-3,4,5, 6-tetrafluorobenzonitrile, the nitrile is then hydrolysed to the target product 2-amino-3,4,5,6-tetrafluorobenzoic acid under the action of a base.
Safety Information:
When using and handling 2-amino-3,4,5,6-tetrafluorobenzoic acid, you need to pay attention to the following safety precautions:
1. Do not directly contact the skin, eyes or respiratory tract, should wear personal protective equipment (such as gloves, goggles and dust mask).
2. Avoid inhalation of its dust, smoke or gas, should be in a well ventilated place of operation.
3. Storage should be placed in a dry, cool, ventilated place, away from the fire and oxidant.
4. Please comply with relevant regulations and management measures, and properly dispose of waste.
