4,4'-Stilbenedicarboxylic Acid(CAS: 100-31-2)

4,4'-Stilbenedicarboxylic Acid (CAS: 100-31-2) is a white crystalline solid with a high melting point of 233-235°C. It has a molecular weight of approximately 246.17 g/mol and is slightly soluble in water. It exhibits moderate reactivity, particularly in ester formation and coupling reactions.

4,4'-Stilbenedicarboxylic Acid is commonly synthesized through a multistep process involving the coupling of 1,3-dibromostilbene with phthalic anhydride in the presence of a Lewis acid catalyst, such as aluminum chloride, followed by hydrolysis to obtain the acid. The reaction is typically carried out in a solvent like dichloromethane, with good selectivity and high yield.

4,4'-Stilbenedicarboxylic Acid (CAS: 100-31-2) finds application in various industries, including pharmaceuticals for the synthesis of organic intermediates, polymers for plasticizers and stabilizers, sensors for chemical detection, and semiconductors for organic electronics due to its unique electrochemical properties.

Proper protective equipment, such as gloves, safety goggles, and lab coats, should be worn when handling 4,4'-Stilbenedicarboxylic Acid (CAS: 100-31-2). Work should be conducted in a well-ventilated area or fume hood to avoid inhalation. In the case of a spill, neutralize the acid with a base and dispose of the mixture according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed safety information.
