  • Applications

    l-Threitol (CAS 2319-57-5) is a polyol that acts as a versatile building block in chemical synthesis and formulations. In industrial manufacturing, it is used as a di- and tetrafunctional polyol component for polyurethanes and polyesters and as a crosslinking/chain-extending agent in coatings, inks, and adhesives. It is also employed as an intermediate for specialty chemicals and pharmaceutical synthesis. In cosmetics and personal care, it can function as a humectant and texture enhancer, improving moisture retention and skin feel. In cleaning and household formulations, it may act as a solvent or co-solvent.
