CAS 288-32-4: Imidazole

Description:Imidazole is a five-membered heterocyclic compound featuring two nitrogen atoms in the ring structure. It is classified as an aromatic compound due to its planar structure and delocalized π-electrons, which contribute to its stability. Imidazole is a colorless, crystalline solid that is soluble in water and polar organic solvents. It has a characteristic basicity, allowing it to act as a weak base, which is attributed to the presence of the nitrogen atoms that can donate a lone pair of electrons. This property makes imidazole an important building block in biochemistry, particularly as a component of amino acids like histidine and in various enzyme active sites. Additionally, imidazole is utilized in pharmaceuticals, agricultural chemicals, and as a ligand in coordination chemistry. Its derivatives exhibit a wide range of biological activities, including antifungal and antibacterial properties. Overall, imidazole's unique structure and reactivity make it a versatile compound in both synthetic and biological contexts.
