  • Applications

    Albanin C (CAS 73343-43-8) is commonly used as an intermediate in organic synthesis and as a solvent or co-solvent in a range of industrial formulations; it may also serve as a processing aid in polymers and coatings, improving dispersion and processing characteristics. In coatings and inks, it can act as a solvent component or reactive diluent; in cosmetics/personal care and fragrances, it may be evaluated as a solvent or fragrance carrier within formulation limits; and in cleaning products or household formulations, it can function as a solvent additive to enhance formulation performance. Its use is subject to local regulations and formulation constraints.
