Adipic acid CAS 124-04-9 is is white crystalline powder, very soluble in methanol, 
ethanol, soluble in acetone, slightly soluble in cyclohexane, negligible in benzene, petroleum ether and insoluble in acetic acid. Adipic acid is the organic compound with the formula (CH2)4(COOH)2. From an industrial perspective, it is the most important dicarboxylic acid mainly used as a precursor for the production of nylon.

Application
- Adipic acid is mainly used as monomer for the production of nylon by a polycondensation reaction with hexamethylene diamine forming nylon 66.
- Other major applications also involve polymers: it is a monomer for production of Polyurethane and its esters are plasticizers, especially in PVC.
- It can also used in food as a flavorant and gelling aid.
- In medicine, adipic acid has been incorporated into controlled-release formulation matrix tablets to obtain pH-independent release for both weakly basic and weakly acidic drugs. It has also been incorporated into the polymeric coating of hydrophilic monolithic systems to modulate the intragel pH, resulting in zero-order release of a hydrophilic drug.
