  • Applications

    Cyprazine (CAS 22936-86-3) is primarily used as a synthetic intermediate across multiple chemical sectors. It may function as a building block for pharmaceuticals, agrochemicals, and other specialty chemicals. It can serve as a solvent or co-solvent and as a processing aid in coatings, inks, and adhesives formulations. In polymer science, it may be employed as a precursor for certain polymers or as an additive to influence processing and performance. It is sometimes evaluated for use in industrial cleaning formulations and related solvent systems, with actual use subject to local regulations and formulation limits.
