Dicyandiamide (DCD)



 

Molecular formula:
C2H4NMolecular weight:84.1 CAS No: 461-58-5

Character:
White crystalline powder, melting point: 209-212°C.

Product Usage:
DCD is a nitrification inhibitor, utilized to increase the efficiency of N fertilization and improve crop yield. DCD can improve crop quality by decreasing nitrate content in crop, reduce soil, ground water, and environment pollution. DCD can be also used as Nitrocellulose stabilizer, vulcanization accelerator, melamine raw material, and medicine, pesticide and dye intermediates.


Mechanism of action
DCD delays bacterial oxidation of NH+4-N to NO-2-N by depressing the activities of nitrosomas bacteria in soil. Fertilizer N will be contained as NH+4-N, decrease conversion of NO-2-N to NO-3-N by reducing NO-2-N content. Meanwhile DMPP may reduce N2O emission to protect environment.


Packaging, storage and transportation:
25 kg cardboard drum, 500 kg bag or according to customer requirements.
