Product Description

Product Name	Cyanamide (Hydrogen Cyanamide) CAS 420-04-2 \| EC No. 206-992-3 Synonyms: carbamonitrile, cyanoamine. Available as 50% aqueous solution and crystal grade (≥95%).
Formula / MW	CH₂N₂ / 42.04
Structure
Product Type	Reactive NCN building block for pharmaceutical, agrochemical, creatine and fine chemical synthesis. Industrial raw material — not a registered plant growth regulator product.
Physical Properties	Crystal: white to off-white solid, melting point 45–46 °C, freely soluble in water and alcohols 50% solution: clear stabilized aqueous solution Dimerizes to dicyandiamide (DCD) under heat or alkaline pH — store cool and closed
Applications	Pharmaceutical: guanidine and aminopyrimidine intermediates; Albendazole, Fenbendazole, Imatinib chemistry Agrochemical: Carbendazim, Amitrole, Pyrimethanil, Sulfoxaflor intermediates Creatine: reaction with sodium sarcosinate to give creatine monohydrate Fine chemicals: guanidine salts, thioureas, heterocycles Plant growth regulator active: used in registered dormancy-breaking products (grapes, kiwifruit) in some markets; registration is market-specific
Packing & Storage	Drums / IBCs (solution) or lined drums (crystal); pack size per order. Keep closed, cool (crystal ≤ 20 °C), dry and away from acids, bases and oxidizers.
Hazard & Transport	Dangerous goods. GHS Danger: toxic if swallowed or on skin (H301, H311), corrosive (H314), skin sensitizer (H317), suspected carcinogen and reproductive toxicant (H351, H361), organ damage on repeated exposure (H373). UN number and class per grade and batch SDS.

FAQ

Are cyanamide and hydrogen cyanamide the same?	Yes. Both names mean CAS 420-04-2, CH₂N₂.
50% solution or crystal — which should I choose?	Solution for aqueous processes and easy dosing; crystal (≥95%) for anhydrous systems and lower freight. Send your target COA and we match the grade.
Why control dicyandiamide (DCD)?	Cyanamide dimerizes to DCD when heated or under alkaline pH. DCD lowers assay and complicates purification, so state your DCD limit when enquiring.
Is cyanamide toxic?	Yes — toxic, corrosive and sensitizing (GHS Danger). Wear gloves, eye protection and protective clothing, work in a ventilated area, and ship as dangerous goods per the SDS.
Can industrial cyanamide be applied to crops?	No. Only registered plant-growth-regulator formulations may be used on crops, following the destination market's label and regulations.
Can you provide COA, SDS and samples?	Yes, for the actual supply grade and batch.
