High Purity Dicyandiamide CAS 461-58-5 Industrial Grade DCDA 99.5%

Dicyandiamide (CAS 461-58-5), also known as Cyanoguanidine or DCDA, is a white crystalline powder with the molecular formula C2H4N4. It is a dimer of cyanamide and serves as a highly versatile nitrogen-rich intermediate.

Dicyandiamide is uniquely valued for its high nitrogen content (approx. 66%) and its latent curing properties. In the adhesives industry, it is the industry-standard latent curing agent for one-component epoxy resins. In agriculture, it acts as a powerful nitrification inhibitor, significantly reducing nitrogen leaching and greenhouse gas emissions. Furthermore, it is a critical building block in the synthesis of guanidine salts and the anti-diabetic medication Metformin.

Multiple Particle Size Grades: We offer superfine micronized DCDA for high-performance adhesives where uniform dispersion is critical.

Low Moisture & Ash: Strictly controlled moisture (≤ 0.2%) ensures consistent reactivity and long-term shelf stability of formulated products.

REACH Registered: Full compliance for the European market, supporting safe and regulated global trade.

Dual-Use Versatility: Trusted by both heavy industry (resins/steel) and life sciences (pharma/agri).

Epoxy Resin Curing Agent Used as a latent hardener in powder coatings, structural adhesives, and carbon fiber prepregs for aerospace and automotive sectors.

Agricultural Fertilizer Additive Functions as a nitrification inhibitor to stabilize ammonium nitrogen in the soil, preventing nitrate leaching and increasing nitrogen efficiency.

Pharmaceutical Intermediate The primary raw material for the synthesis of Metformin Hydrochloride and other biguanide-based drugs.

Water Treatment Used in the production of dicyandiamide-formaldehyde decoloring agents for treating industrial wastewater (textile/dyeing).

Steel Industry Utilized as a nitrogen-increasing agent (nitriding) during the surface hardening process of steel.
