488-48-2 - Introduction
Tetrabromobenzoquinone (Tetrabromo-p-benzoquinone) is a chemical compound whose chemical formula is C6Br4O2. The following is a description of the properties, uses, preparation and safety information of tetrabromoquinone:
Nature:
-Tetrabromobenzoquinone is a light yellow to brown crystal, soluble in organic solvents such as ether and benzene, insoluble in water.
-It has a special aroma.
-Tetrabromobenzoquinone is sensitive to air and light and is easy to decompose.
Use:
-Tetrabromobenzoquinone is widely used as an oxidant in organic synthesis, especially for oxidizing divalent sulfoxide (sulfine) to divalent thiol (sulfenic acid).
-It can also be used for dye synthesis and aniline formaldehyde reaction.
Preparation Method:
-Tetrabromobenzoquinone can be prepared by bromination of p-benzoquinone. A common method is to react benzoquinone with bromine or ferrous bromide under alkaline conditions to produce tetrabromobenzoquinone.
Safety Information:
-Tetrabromobenzoquinone has certain toxicity and irritation, please take care to avoid contact with skin, eyes and inhalation.
-Good laboratory safety measures should be taken during operation, and chemical protective gloves, glasses and laboratory coats should be worn.
-Avoid direct sunlight and high temperature during storage and handling.
