2-Bromo-9,10-anthraquinone(CAS: 572-83-8)

2-Bromo-9,10-anthraquinone is a yellow crystalline solid with a molecular formula of C14H8BrO2 and a molecular weight of approximately 259.05 g/mol. It has a low water solubility and high solubility in organic solvents such as acetone and ethanol. This compound is relatively stable but can undergo bromine substitution reactions under certain conditions. Its crystalline form is typically monoclinic.

2-Bromo-9,10-anthraquinone is commonly synthesized by the bromination of 9,10-anthraquinone using bromine in an appropriate solvent like acetic acid. The reaction proceeds via electrophilic aromatic substitution, providing good yield and selectivity. Catalysts such as iron(III) chloride can be used to improve the reaction rate and selectivity.

2-Bromo-9,10-anthraquinone is primarily used in the pharmaceutical and chemical industries for the synthesis of dyes and intermediates. It is also used in the production of organic semiconductor materials and as a reagent in analytical chemistry. Its applications include dye intermediates, organic electronic materials, and chemical sensors.

When handling 2-Bromo-9,10-anthraquinone, appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. This compound should be handled in a fume hood to minimize inhalation risks. Spills should be cleaned up with appropriate absorbents, and the area should be well-ventilated. Safety data sheets (SDS) should be consulted for detailed handling and emergency response information.
