NITRALZ®
Alzchem - we stand for tradition and innovation
Located in the south of Germany, Alzchem stands for tradition and innovation: Based on more than 50 years of nitriles experience we have developed and launched several new products using our technology in recent years.
We offer reliability, quality, flexibility and innovation: State-of-the-art process controls, short production changeover, German precision, proprietary catalysts and a safe supply chain.
We produce "green": Our gas-phase technology stands for low emissions and reduced waste. Our on-site incinerator converts off-gas to water and carbon dioxide, and in the case of chlorinated benzonitriles to hydrochloric acid which is used in other processes on site.

Pharmaceuticals
Nitriles for the production of API's
NITRALZ® One Source – INNOVATIVE SOLUTIONS
Our NITRALZ® products are used as intermediates for API (active pharmaceutical ingredients) production.
Alzchem is the independent and reliable Western source for many nitriles / gas phase reactions.
Via special distillation we achieve high quality and purity as an independent reliable western source. Furthermore we are proud of our in-house catalyst development. By applying our extensive catalyst Know-How and innovation thoughts we have branched out into additional groups of molecules, like ketones (e.g. 3-Acetylpyridine).
To meet your needs our R&D works closely with your team to develop advanced chemical solutions.
Thus the production from gram scale to ton scale is no problem for us.
High quality nitriles via gas phase technology MADE IN GERMANY:
We offer a broad product portfolio for the production of APIs.
Alzchem features e.g. 2-Chlorobenzonitrile (CAS No. 1867-66-9) available from stock in three different qualities:
- Standard Quality – as organic building block for industrial use.
- Extra Pure Quality – mainly used for the production of Ketamine hydrochloride.
- Super Quality – with the highest purity of min. 99,5%, an outstanding quality is available for active pharmaceutical ingredients.
Furthermore our NITRALZ® 4-Aminobenzonitrile serves as essential intermediate for APIs like Dabigatran or Frovatriptan.
Another product we would like to highlight is our 3-Acetylpyridine, which is used for the production of the API Imatinib.
Solvents
NITRALZ® One Source – INNOVATIVE SOLUTIONS
Nitriles are also applied as special high quality solvents for individual requirements. These high quality solvents are used in agriculture, pharmaceutical and industrial application. Aliphatic nitriles and the aromatic derivative, Benzonitrile, are attracting increasing attention as specialty solvents in organic synthesis.
Their dipolar, aprotic properties, their solvent characteristics, such as the dissolution capacity of polar chemicals and the liquid range allow the user to choose the ideal solvent for every application. What´s more, they are stable and inert in many chemical conversions and can be used at a wide temperature range.
