4-Bromo-2,5-difluoronitrobenzene - Introduction
1-Bromo-2, 5-difluororo-4-nitrobenzene, also known as bromodifluoronitrobenzene (BDFNB), has the following properties and uses:
Properties: BDFNB is a yellow crystalline solid with a high melting point and boiling point. It is insoluble in water at room temperature, but soluble in some organic solvents such as ethanol and ether. BDFNB is an organic compound, which is dangerous, so it is necessary to pay attention to safety when using and handling.
Uses: BDFNB is mainly used as an intermediate in organic synthesis and is used to prepare other organic compounds. It can be used as a synthetic raw material for pesticides, dyes and certain drugs. In addition, BDFNB can also be used as a reagent and catalyst.
Preparation method: The method of preparing BDFNB is generally achieved through a series of chemical reaction steps. One common method is to react 2-bromo-5-fluoro-4-nitrobenzene with bromine under appropriate conditions to obtain BDFNB. This process requires some special laboratory equipment and chemical knowledge.
Safety information: BDFNB is an organic compound with a certain degree of danger. Wear protective gloves, glasses and protective clothing when touching or handling BDFNB to avoid direct contact with skin and eyes. Avoid contact with combustibles, strong oxidants and strong acids during operation and storage to prevent accidents. In addition, BDFNB should be kept away from fire and high temperature environment, and stored in a dry and cool place. If ingested or inhaled by mistake, seek medical attention immediately.
