TETRABROMOHYDROQUINONE - Introduction
2,3,5,6-tetrabromohydroquinone(2,3,5,6-tetrabromohydroquinone) is an organic compound with the chemical formula C6H2Br4O2. The following is a description of its nature, use, preparation and safety information:
Nature:
2,3,5,6-tetrabromohydroquinone is a colorless to pale yellow crystalline solid with a bitter taste. It has a melting point of about 176-180 ° C. It is less soluble in water and better soluble in organic solvents such as ethanol and dimethylformamide.
Use:
2,3,5,6-tetrabromohydroquinone has certain chemical activity and oxidation. It can be used as an intermediate or starting material in organic synthesis, for example for the preparation of pigments, fluorescent dyes, antioxidants and like compounds. In addition, it can be used as a reagent in research and analytical chemistry.
Method:
2,3,5,6-tetrabromohydroquinone can be prepared by bromination of p-Hydroxybenzoic acid. The specific step is to react hydroxybenzoic acid with hydrochloric acid to generate benzoic acid ammonium salt, and then through bromination reaction, using bromine to control the reaction conditions, to obtain 2,3,5,6-tetrabromohydroquinone.
Safety Information:
2,3,5,6-tetrabromohydroquinone is a toxic substance that is irritating and dangerous. Contact with skin and eyes can cause irritation and burns. Personal protective equipment such as protective gloves and goggles should be worn during operation, and the operating environment should be well ventilated. Avoid inhaling dust or gas. When storing and handling, please follow the relevant safety regulations to avoid reaction with other chemicals. If exposed or inhaled, seek medical help immediately.
