HPLC Method for Analysis of Cyanamide, Dicyandiamide and Urea on Primesep S Column with Varies Mobile Phases
May 1, 2023
Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies
HPLC Method for Analysis of Cyanamide, Dicyandiamide, Urea on Primesep S Column by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Cyanamide, Dicyandiamide, Urea
Cyanamide (H2CN2) is a highly reactive and toxic compound used in the production of fertilizers, pharmaceuticals, and other chemicals. It can be used as a soil fumigant to control pests and weeds.
Dicyandiamide (C2H4N4) is a white crystalline solid that is often used as a slow-release fertilizer. It is also used in the production of pharmaceuticals, dyes, and resins. Dicyandiamide can also be used as a nitrification inhibitor in agriculture to reduce the loss of nitrogen from the soil.
Urea (CO(NH2)2) is a white crystalline solid that is widely used as a fertilizer due to its high nitrogen content. It is also used in the production of plastics, resins, and adhesives. Urea is also used in the manufacturing of animal feed, and as a raw material in the production of many industrial chemicals. In addition, it is also used as a component in certain skin creams and cosmetics due to its moisturizing properties.
Using a Primesep S normal-phase column and a mobile phase consisting of water and Acetonitrile (MeCN) with no buffer, Cyanamide, Dicyandiamide and Urea can be retained, separated, and analyzed. This analysis method can be UV detected at 200 nm.

HPLC Separation of Dicyandiamide, 1,2,4-Triazole, 3-Methylpyrazole on Primesep 100 Column
December 20, 2019
Dicyandiamide, or cyanoguanidine, is used as a curing agent for epoxy resins. 1,2,4-triazole, is a heterocycle used primarily as an antifungal but has other uses in the pharmaceutical industry as well. 3-methylpyrazole is used in nitrogen fertilizers. All three compounds are structurally similar and can be separated in HPLC using Primesep 100 reverse-phase (RP) mixed-mode cation-exchange (CX) column using acetonitrile (ACN) and water mobile phase with phosphoric acid buffer and UV detected at 200nm and 220nm.
