131747-42-7 - Introduction
6-(Trifluoromethyl) picolinic acid, also known as TFMPA, has the chemical formula C8H4F3NO2. The following is a presentation of information on the nature, use, formulation and safety of TFMPA:
Nature:
1. Appearance: TFMPA is a solid, common white crystal or white powder.
2. Solubility: TFMPA is soluble in most organic solvents, such as methanol, ethanol and ethyl acetate.
3. Thermal stability: TFMPA will decompose at high temperature.
4. Acidity: TFMPA is a weak acid with acidity.
Use:
1. As a catalyst: TFMPA can be used as a catalyst in organic synthesis, for example, in esterification and acylation reactions.
2. chemical intermediates: TFMPA can be used as an intermediate for the synthesis of other compounds, such as for the preparation of pesticides, pharmaceuticals and dyes.
Preparation Method:
TFMPA can be prepared by reacting benzylidene fluoride with picolinic acid to produce the target product. The reaction is usually carried out at a certain temperature and reaction time.
Safety Information:
1. TFMPA is an organic compound, and attention should be paid to appropriate laboratory operations and protective measures.
2. in case of contact with skin or eyes, rinse immediately with plenty of water.
3. When using or storing TFMPA, attention should be paid to sealing and storing, and avoid contact with oxidants and high temperatures.
4. When handling TFMPA, it is recommended to use a well-ventilated environment and avoid inhaling its dust or smoke.
