  • Applications

    Compound (3S,3'R,5R,6S)-beta,beta-Carotene-3,3',5,6(5H,6H)-tetrol (CAS number: 99664-49-0) is primarily used as an intermediate in carotenoid synthesis and as a building block for polar carotenoid derivatives in pharmaceutical research and related fields. It can be explored as an antioxidant additive and cosmetic colorant in personal-care formulations, leveraging carotenoid-like activity while its tetrol functionality may improve dispersibility. In specialty coatings, inks, and plastics, it may serve as a pigmenting additive for niche formulations. It may also function as a synthetic precursor toward vitamin A-related compounds in chemical manufacturing and is used in analytical and method-development work in carotenoid chemistry as a reference material or research reagent.
