HPLC Method for Separation of Urea and Thiourea on Primesep S Column
July 25, 2023
Separation type: Liquid Chromatography Mixed-mode
HPLC Method for Separation of Thiourea, Urea on Primesep S Column by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Thiourea, Urea
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.
Thiourea is a versatile chemical compound with the formula (NH2)2CS. It is structurally similar to urea, except that the oxygen atom is replaced by a sulfur atom. It is a white crystalline solid when pure.
Thiourea is used in a variety of applications. It is a reagent in organic synthesis, often used in the toning of silver-gelatin photography prints, as a component of hair preparations and bleaches, and as a radioprotective agent in cancer therapy.
In agriculture, thiourea is used as a soil treatment agent to promote germination and stimulate flowering and fruiting.
Using a Primesep S normal-phase column and a mobile phase consisting of water and Acetonitrile (MeCN) with no buffer, Thiourea and Urea can be retained, separated, and analyzed. This analysis method can be UV detected at 200 nm.

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.
