CAS 104-98-3: Urocanic acid

Description: Urocanic acid is an organic compound with the chemical formula C6H6N2O2, classified as an imidazole derivative. It is a colorless to pale yellow crystalline solid that is soluble in water and alcohol. Urocanic acid is primarily found in the skin, where it plays a role in the photoprotection of cells against ultraviolet (UV) radiation. It is formed from the breakdown of histidine, an amino acid, and is involved in various biological processes, including the regulation of immune responses. The compound exhibits a unique property of undergoing tautomerization, existing in both the keto and enol forms, which can influence its reactivity and biological activity. Urocanic acid has been studied for its potential therapeutic applications, particularly in dermatology, due to its ability to absorb UV light and its role in skin health. Additionally, it has been investigated for its effects on immune modulation, making it a subject of interest in research related to skin disorders and cancer.
