Guanidine Salts

High-quality Guanidine Salts for biotechnological, diagnostic and pharmaceutical applications

As a major world producer of the starting material, dicyandiamide, AlzChem can offer guanidine salts with a wide range of applications from the automotive to the biopharmaceutical industry:

Guanidine Nitrate is a key ingredient for the manufacture of propellants for airbags. It is also used in fireworks and is the starting material for captive production of Nitro Guanidine.

Technical Guanidine Hydrochloride, Guanidine Phosphate and Guanidine Sulfamate have applications as flame retardants for textiles and wood, as well as for electroplating.

Ultrapure Guanidine Carbonate has application in the cosmetics field.

Due to their chaotropic character both ultrapure Guanidine Hydrochloride and Guanidine Thiocyanate are used as protein denaturants in the development and production of biopharmaceuticals and their generic versions called biosimilars. In addition, they are useful for the extraction of DNA and RNA in molecular diagnostics.

A prime example of this are our Melflock® products, which are mostly used as flocculants in the paper and water treatment industries. Because of the backward integration of our most important raw material ‘Dicyandiamide’ we can ensure the availability of all our Melflock® products. The diligent work of our customer service and logistic department is the reason why we can keep up with regular delivery times within Europe, whereas the European transport market itself is running into trouble...

Trostberg. Amidines are organic chemical compounds with an NCN structure, meaning a typical nitrogen-carbon-nitrogen sequence. These types of chemicals are one of AlzChem’s core competencies. NCN structures are contained in many biologically active molecules, which is why a general new synthesis method is so important to the development and production of active ingredients in pharmaceuticals and crop protection. Amidines to this point have been difficult to synthesize, particularly without...
