High Purity 99.5% Guanidine Carbonate Manufacturer | CAS 593-85-1

• Guanidine carbonate is an organic guanidine salt compound with the chemical formula CH5N3·2CH2O3, appearing as a white crystalline powder formed by the combination of guanidine and carbonic acid. In the category of food additives, guanidine carbonate is not a direct food additive for consumption, but a food processing aid (e.g., used in the synthesis of food contact materials and surface treatment aids for food processing equipment). In industrial classification, it belongs to guanidine salt compounds in fine chemicals.
• Its core role in the industry is: serving as an organic synthesis intermediate for the synthesis of food-related polymer materials (such as resins for food packaging), regulating the reaction characteristics of chemical raw materials used in food processing, and also acting as a key raw material in the pharmaceutical, electroplating, and agricultural fields.

• Good water solubility, with an aqueous solution showing weak alkalinity
• Strong thermal stability, not easy to decompose at room temperature
• Excellent guanidination reaction activity, an important guanidinating reagent for organic synthesis
• No obvious pungent odor, high safety in storage and operation
• Can form complexes with various metal ions, suitable for surface treatment processes such as electroplating

 Guanidine carbonate is commonly used in:

• Synthesis of food contact materials (e.g., preparation of polyamide resins for food packaging and food-grade adhesives)
• ​Synthesis of pharmaceutical intermediates (production of active pharmaceutical ingredients such as antibiotics and hypoglycemic drugs)
• ​Electroplating industry (as a brightener and conductive salt in electroplating solutions for metal plating treatment of food processing equipment)
• ​Preparation of agricultural chemicals (raw material for the synthesis of slow-release nitrogen fertilizers and plant growth regulators)
• ​Textile printing and dyeing (antistatic finishing agent and dyeing assistant for food-grade textile fabrics)

1. Q: Can guanidine carbonate be directly added to food?

A: No. It is a food processing aid (for food contact materials/equipment treatment), not a direct food additive.

​

2. Q: What are the storage requirements for guanidine carbonate?

A: Seal in a cool, dry, ventilated warehouse; avoid fire, heat, strong acids and oxidants. 24-month shelf life at room temperature.

​

3. Q: How is guanidine carbonate different from guanidine hydrochloride in application?

A: Guanidine carbonate is for organic synthesis, electroplating and food contact materials; guanidine hydrochloride is mainly used as a protein denaturant and pharmaceutical intermediate.

​

4. Q: What is guanidine carbonate’s role in electroplating?

A: It acts as a brightener and conductive salt to improve plating brightness/uniformity and solution conductivity.

​

5. Q: Does guanidine carbonate dissolve in water and react with metal ions?

A: It has good water solubility (weakly alkaline solution) and forms complexes with copper, nickel, zinc and other metal ions.

6. Q: What's the material packed when shipped?

A: Usually it's 25kg/bag packed and on pallets when sea shipped which can guarantee stability.

7.Q: What's the payment term when want to buy?

A: Please contact our company via Email, WhatsApp or Verbally for further communication.

8.Q: What's the lead time of guanidine carbonate?

A: Lead time could be commonly 2-3 weeks or contact us for more details.
