Dicyandiamide
1. Basic Product Information
Product Name: Dicyandiamide
Abbreviation: DCD, Dicy
CAS Number: 461-58-5
Molecular Formula: C2H4N4
Molecular Weight: 84.08
Synonyms: Dicyanodiamide, 2-Cyanoguanidine, Cyanoguanidine
Product Category: Nitrogen fine chemical intermediate, epoxy curing agent, fertilizer nitrification inhibitor, pharmaceutical synthetic precursor, dye fixing agent
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White crystalline powder
- Odor: Odorless
- Solubility: Slightly soluble in cold water, soluble in hot water; soluble in ethanol, methanol; insoluble in ether, benzene and aliphatic hydrocarbons
- Melting Point: 209–212 °C (decomposes)
- Density (20 °C): 1.41 g/cm3
- Hygroscopicity: Slightly hygroscopic under high humidity air
- Aqueous Stability: Stable in neutral and weakly acidic aqueous solutions; slow hydrolysis under long-term heating with strong acid or strong alkali to generate urea and ammonia
Chemical Characteristics
- Molecular Structure: Guanidine derivative containing cyano group, multi-nitrogen heterocyclic precursor structure
- Core Functional Mechanism: Multi-nucleophilic nitrogen-containing compound; used for cyclization synthesis of guanidine salts, melamine, biguanide series products; curing agent for epoxy resin; nitrification inhibitor to slow nitrogen loss in soil
- Photostability: Stable under normal sealed storage, no obvious light-induced discoloration
- Thermal Stability: Stable below 180 °C; above melting point, thermal decomposition releases toxic nitrogen-containing cyanide volatile fumes
- Chemical Compatibility: Compatible with neutral inorganic salts and polar solvents; incompatible with strong oxidants, concentrated strong acids and heavy metal salts
3. Main Application Fields
- Core Application: Epoxy Resin Curing Agent
Latent curing agent for single-component epoxy coatings, adhesives and electronic packaging materials, featuring long storage stability at room temperature - Agricultural Nitrification Inhibitor
Additive for compound nitrogen fertilizers to inhibit soil nitrifying bacteria, reduce nitrogen leaching loss and improve fertilizer utilization efficiency - Pharmaceutical Synthetic Intermediate
Key raw material for synthesizing metformin hydrochloride, biguanide antibacterial and hypoglycemic APIs - Fine Chemical Raw Material
Starting material for manufacturing melamine, guanidine nitrate, cationic dye fixing agents and water treatment biocides - Metal Surface Treatment Auxiliary
Additive for electroplating brightener and metal corrosion inhibitor formulations
4. Platform Category & Product Group Guidance
