5Hydroxyisophthalic

5-Hydroxyisophthalic acid is an organic compound with the chemical formula C8H6O5. It is a derivative of isophthalic acid, which is a benzene dicarboxylic acid. In 5-hydroxyisophthalic acid, a hydroxyl group (OH) is attached to the benzene ring at the 5th position, relative to the two carboxylic acid groups (COOH) located at the 1 and 3 positions. This molecule is also known as 5-hydroxybenzene-1,3-dicarboxylic acid. It appears as a crystalline solid and is soluble in certain organic solvents and water, depending on the pH.

The synthesis of 5-hydroxyisophthalic acid can be achieved through various chemical routes, often involving the oxidation of appropriately substituted aromatic precursors. Its chemical properties are influenced by the presence of both the hydroxyl group and the two carboxylic acid groups. These functional groups make it a versatile molecule for chemical reactions, particularly in the synthesis of polymers and other complex organic structures. It can undergo esterification, etherification, and reactions characteristic of carboxylic acids.

5-Hydroxyisophthalic acid finds applications as a building block or intermediate in the synthesis of specialty chemicals, pharmaceuticals, and advanced materials. Its potential use in the development of metal-organic frameworks (MOFs) has also been explored, where it can act as a linker molecule due to its coordinating functional groups. Further research continues to investigate its broader applicability in various chemical and material science fields.
