  • Applications

    Sodium dicyanamide (CAS 1934-75-4) serves as a versatile cyanamide source and salt with several real-world applications: as an intermediate in organic synthesis to access dicyanamide- or cyanamide-containing compounds; as a building block for cyanamide-based polymers and crosslinking resins used in polymer chemistry; as a component or electrolyte salt in non-aqueous battery formulations for lithium- or sodium-ion cells; in coatings, inks, and adhesives it can function as a cyanamide-derived reagent to introduce cyano groups during curing or functionalization; and it is studied as a building block for ionic liquids and nitrile-functional materials. It has also been explored for potential flame-retardant roles in certain polymer formulations under specific conditions.
