  • Applications

    Dipotassium 2-(2-hydroperoxy-2-oxoethyl)-2-hydroxybutanedioate (CAS 232281-44-6) is a hydroperoxide-containing tartrate derivative that is considered for use as a radical initiator and oxidative agent in materials chemistry. It may be employed as a polymerization initiator or crosslinking agent in polymers, and as a curing/initiating component in coatings, paints, and inks. It can also serve as an intermediate in organic synthesis and as an oxidative reagent in industrial processing, subject to proper handling and controls. In addition, it may be evaluated for use in cleaning formulations and in pharmaceutical or specialty chemical synthesis routes, depending on local regulations and formulation limits.
