9,10-Anthracenedicarboxylic acid(CAS: 73016-08-7)

9,10-Anthracenedicarboxylic acid is a white crystalline solid with a molecular weight of approximately 244.24 g/mol. It has a high solubility in hot water and poor solubility in cold water. The acid is known for its strong reactivity, particularly towards nucleophilic substitution and condensation reactions. It is highly stable in dry air but can decompose in the presence of moisture and heat.

9,10-Anthracenedicarboxylic acid can be synthesized via the Wittig reaction, where anthracene is treated with phosphorus ylide and a strong base like n-butyllithium. Another method involves the oxidative cleavage of anthracene-9,10-dione using hydrogen peroxide in the presence of a catalyst like manganese dioxide. These processes typically yield high selectivity and good to excellent yields.

9,10-Anthracenedicarboxylic acid is primarily used in the production of polyesters, as a monomer for the synthesis of polymers, and in the development of organic sensors and semiconductors. It is also utilized in the pharmaceutical industry for certain drug intermediates and in the formulation of materials for electronic applications.

When handling 9,10-Anthracenedicarboxylic acid, laboratory personnel should wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. The substance should be stored in a cool, dry place away from direct sunlight and heat. Spills should be handled using appropriate absorbents, and the area should be cleaned thoroughly. It is advisable to consult the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
