Dicyanodiamide (DCD DICY) CAS 461-58-5 powder

Dicyanodiamide, commonly abbreviated as DCD or DICY, is a widely used organic chemical compound with CAS 461-58-5. It is mainly supplied in powder form, which is easy to store, transport and use, making it a preferred choice for global import purchasers in various industries. This page provides detailed information about Dicyanodiamide, including its aliases, physical properties, product specifications, applications, and related services to help purchasers make informed decisions.

Product Aliases

Dicyanodiamide has multiple aliases in the industry, including Cyanoguanidine, Dicyanodiamine, Dicyandiamide, DCDA, Cyanoguanidine, and Dimeric Cyanamide. These aliases are commonly used in different regions and application fields, but they all refer to the same chemical compound with the molecular formula $$C_2H_4N_4$$.

Physical Properties & Characteristics

Dicyanodiamide is a white rhombic crystalline powder with no odor, showing excellent stability under dry conditions. Its key physical properties are as follows: density is 1.400 g/cm³ (25/4℃), melting point ranges from 207–209 ℃, and boiling point is about 252 ℃ (decomposes). It is slightly soluble in water (2.26% at 13℃, more soluble in hot water) and ethanol (1.26% at 13℃), soluble in acetone, liquid ammonia, ethylene glycol and dimethylformamide, and almost insoluble in ether, benzene and chloroform. The product is non-flammable and will decompose slowly when the aqueous solution exceeds 80℃, releasing ammonia gas; it will melt and release intense heat near the melting point to form melamine.

Product Applications

Dicyanodiamide (CAS 461-58-5) has a wide range of applications in chemical, agricultural, electronic and other industries, and its main uses are as follows:

Chemical Intermediate: It is an important raw material for guanidine salts and melamine derivatives. Reacting with acids can produce various guanidine salts; reacting with phenyl nitrile can obtain benzoguanamine, which is an intermediate for coatings, laminates and molding powders. It can also be used to produce thiourea, nitrocellulose stabilizers, rubber vulcanization accelerators and steel surface hardeners.

Epoxy Resin Curing Agent: As a latent curing agent for epoxy resins, it is used to prepare one-component epoxy adhesives. When the particle size of Dicyanodiamide is ≤5μm, it can form a suspension in epoxy resins without precipitation, improving the mechanical and physical properties of resins, and is widely used in electronic, electrical and construction fields.

Agricultural Field: As a nitrogen fertilizer additive, it can control the activity of nitrifying bacteria, adjust the conversion rate of nitrogen fertilizer in soil, reduce nitrogen loss and improve fertilizer use efficiency. It is also used in the production of compound fertilizers.

Dye Fixing Agent: The Dicyanodiamide resin prepared by reacting with formaldehyde can be used as a fixing agent for direct dyes, as well as a post-treatment fixing agent for dyeing cotton, silk and other fabrics, improving the adhesion and durability of dyes.

Water Treatment: It is a key monomer or raw material for synthesizing decolorizing flocculants, which can be compounded with aluminum salts, iron salts and other inorganic coagulants to enhance the flocculation effect on colored substances, and is suitable for the treatment of textile printing and dyeing wastewater, dye production wastewater and paper wastewater.

Metal Detection: It can be used to detect metals such as cobalt, nickel, copper and palladium, providing a reliable tool for metal analysis and detection.

Product Compliance & Service

Dicyanodiamide has passed REACH registration, complying with EU chemical regulations and meeting the import requirements of European markets. For the safety of use, MSDS download is available, providing detailed safety information, handling methods and emergency measures to ensure the safety of operators and compliance with relevant national and regional regulations.
