  • Applications

    Guanidine, N,N'''-1,4-butanediylbis-, sulfate (CAS 36587-93-6) is a bis-guanidinium sulfate salt that serves as a multifunctional building block in chemical synthesis and materials development. In industry, it is commonly used as an intermediate for preparing guanidinium-containing polymers and ligands, and it can act as a crosslinking or cationic functional additive to improve network formation and adhesion in coatings, inks, and adhesive formulations. It is also evaluated as a pharmaceutical/medicinal chemistry building block for constructing guanidine-containing molecules, and it is of interest in electronics-relevant research as a model or component for ion-conducting polymer systems and electrolytes. Its use is subject to local regulations and formulation limits.
