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.

Separation of Cyanamide on Newcrom R1 HPLC column
May 16, 2018
Cyanamide can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.
Application Column
Newcrom R1
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
