3-broMo-2,5-dihydrofuran-2,5-dione - Introduction
bromomaleic anhydride is an organic compound with the chemical formula C4H3BrO3. It is a colorless crystal or white crystalline solid with a special pungent odor. bromomaleic anhydride is a strong electron affinity agent, and can occur conjugate addition reaction.
bromomaleic anhydride are mainly used as intermediates in organic synthesis, widely used in pharmaceutical, dyes, adhesives and other fields. It can be used in the synthesis of carboxylic acids, esters, alcohols and fatty amides and other compounds. In addition, bromomaleic anhydride can also be used as initiators, photosensitizers, and diazotizing agents.
The method for preparing bromomaleic anhydride is usually obtained by reacting bromomaleic acid and anhydride. One of the common preparation methods is to react bromo-maleic acid with anhydrous anhydride in an ether solvent to produce the target product.
When using bromomaleic anhydride, you need to pay attention to its safety. It is irritating and corrosive, and direct contact with skin and eyes should be avoided. In the industrial process, appropriate safety measures must be taken, such as wearing protective gloves, safety glasses and respiratory protection equipment. In addition, it should be stored in a dry and well-ventilated place, separated from oxidizing agents, reducing agents, acids, alkalis and other chemical substances to prevent them from reacting with other chemical substances.
