1245648-36-5 - Introduction
4-Fluoro-7-bromoisatin is an organic synthetic dye with the chemical name of 4-fluoro-7-bromo-2-hydroxy-1, 3-diphenyl indolo [n,n-dimethyl] porphyrin-3, 8,10, 12-tetraone.
4-Fluoro-7-bromoisatin has a brilliant red color and is a highly stable dye that is soluble in organic solvents. It is red in acidic conditions and blue in alkaline conditions. This dye is widely used in optical and electronic fields, and is often used in dyeing reagents, inks, rubber and plastic dyes.
The method for preparing 4-fluoro-7-bromoisatin is mainly achieved by an oxidation reaction of phenol. Specific steps include reacting phenol with potassium bromide to produce bromophenol, which is then reacted with ferric chloride to produce 4-bromo-2-hydroxy-1, 3-diphenylindole. Finally, a fluorine atom is introduced by a fluorination reaction to produce 4-fluoro-7-bromoisatin.
Regarding the safety information of 4-fluoro-7-bromoisatin, it has certain toxicity to the environment and may have an impact on aquatic organisms. During use, appropriate protective measures should be taken to avoid contact with the skin and inhalation of distilled gases. At the same time, the disposal of waste should comply with relevant environmental regulations and disposal regulations.
