Description

(6'ξ)-3,3'-Dihydroxy-β,ε-Carotene-2',4-Dione is a specialized, high-value carotenoid derivative, also known as a keto-carotenoid. This compound matters for its role as a potent natural colorant and a precursor in the synthesis of other valuable apocarotenoids, offering vibrant yellow to red hues and potential bioactive functions. It is primarily needed by manufacturers in the nutraceutical, food and beverage, and cosmetic industries seeking natural, stable coloring agents and functional ingredients.

Application

• As a natural colorant in food and beverage products, providing stable yellow and orange shades.
• A key intermediate in the synthesis of high-value apocarotenoids like crocetin and saffron analogs.
• An active ingredient in premium dietary supplements and nutraceuticals for antioxidant support.
• A coloring agent in cosmetic and personal care formulations such as creams, lotions, and lipsticks.
• Used in animal feed and aquaculture to enhance the coloration of poultry, fish, and crustaceans.
• As a reference standard in analytical laboratories for quality control and research purposes.
• Potential applications in functional foods and pharmaceutical formulations for its bioactive properties.
