1,4-Difluoro-2-isothiocyanatobenzene - Introduction
3-fluoro-4-chorobenzyl bromide, chemical formula C7H4ClFBr, is an organic compound. The following is a description of its nature, use, formulation and safety information:
Nature:
-Appearance: colorless liquid or crystal.
-Solubility: Soluble in organic solvents such as ethanol and dimethylformamide.
-Melting point: About 50-60 degrees Celsius.
-Boiling point: About 220-230 degrees Celsius.
Use:
-3-fluoro-4-chloride bromide is an important raw material in organic synthesis. It can be used as a ligand of metal catalyst and participate in organic synthesis reaction.
-It can also be used for research and development in the pharmaceutical field, for the synthesis of drugs or pharmaceutical intermediates.
Method:
-A common preparation method is to react 3-fluorobenzyl alcohol with hydrogen oxide to prepare 3-fluorobenzaldehyde, the 3-fluorobenzaldehyde is then reacted with dibromomethane to give 3-fluoro-4-bromobenzaldehyde. Finally, 3-fluoro-4-bromobenzaldehyde was converted to 3-Fluoro-4-chlorobenzyl bromide by chlorination.
Safety Information:
- 3-Fluoro-4-chlorobenzyl bromide should be operated in a well-ventilated place to avoid inhalation or contact.
-Wear protective gloves, goggles and protective clothing when using.
-Avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water and seek medical help.
-Avoid contact with oxidants and high-temperature substances during use and storage to avoid chemical reactions and fires.
-Please store, transport and handle in accordance with relevant laws and regulations.
