CAS 7542-45-2

3,3'-dihydro-β,β-carotene-4,4'-dione

Description:

3,3'-Dihydro-β,β-carotene-4,4'-dione, with the CAS number 7542-45-2, is a carotenoid derivative characterized by its vibrant orange-red color, typical of many carotenoids. This compound features a polyene structure with conjugated double bonds, contributing to its strong light absorption properties, particularly in the visible spectrum. It is a diketone, indicating the presence of two carbonyl (C=O) groups, which can influence its reactivity and stability. The presence of these functional groups may also affect its antioxidant properties, making it of interest in various biological and nutritional studies. In terms of solubility, carotenoids are generally more soluble in organic solvents than in water, which is consistent with this compound. Its potential applications span from food coloring to health supplements, given the role of carotenoids in human health, particularly in vision and skin protection. However, specific stability and reactivity details would depend on environmental conditions such as pH, temperature, and exposure to light.
