Description

cis-5,6-Dihydro-5,6-Dihydroxy-Carotene is a specific, chemically defined derivative of β-carotene, characterized by its cis-configuration and the addition of hydroxyl groups at the 5,6-positions. This compound serves as a valuable intermediate and reference standard in the synthesis and analysis of carotenoids and retinoids, offering precise structural control for research and development. It is primarily sought by manufacturers and researchers in the pharmaceutical, nutraceutical, and fine chemical sectors for applications requiring high-purity, well-characterized carotenoid precursors.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized retinoids and vitamin A analogs for drug development.
• Nutraceutical Research: Acts as a precursor or reference compound in the study of carotenoid metabolism and bioavailability.
• Analytical Standard: Serves as a high-purity certified reference material (CRM) for HPLC, LC-MS, and other analytical methods to quantify carotenoids in complex matrices.
• Fine Chemical Synthesis: A key building block for creating novel carotenoid derivatives with potential antioxidant or colorant properties.
• Cosmetic Ingredient Research: Investigated for potential use in skincare formulations due to its structural relation to provitamin A compounds.
