Squaric acid is a white, crystalline solid that is soluble in water and organic solvents. Squaric acid is a dicarboxylic acid, meaning it contains two carboxylic acid groups (-COOH) attached to a four-membered ring. It is named after its square-shaped molecular structure. Squaric acid has several applications in organic synthesis and as a starting material for the production of other compounds. It can be used as a building block for the synthesis of various pharmaceuticals, dyes, and polymers. It is also used in the preparation of squaraine dyes, which are fluorescent dyes used in imaging and sensing applications.
