Nitriles

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.

Nitriles for pharmaceuticals

NITRALZ® One Source – INNOVATIVE SOLUTIONS

Our NITRALZ® products are used as intermediates for the API (active pharmaceutical ingredient) production.

AlzChem is the independent and reliable Western source for many nitriles / gas phase reactions.

By special distillation we achieve high quality and purity of our nitriles. 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.

Did you know that …

Over 30 nitrile-containing pharmaceuticals are prescribed for a diverse variety of medicinal indications with more than 20 additional nitrile-containing leads in clinical development.
The nitrile group is quite robust and, in most cases, is not readily metabolized but passes through the body unchanged. The types of pharmaceuticals containing nitriles are diverse, from vildagliptin, an antidiabetic drug, to anastrozole, which is the gold standard in treating breast cancer. In many instances the nitrile mimics functionality present in substrates for enzymes, whereas in other cases the nitrile increases water solubility or decreases susceptibility to oxidative metabolism in the liver. The nitrile functional group is found in several drugs. (Fleming et al. 2010: 7902)

Solvents

NITRALZ® One Source – INNOVATIVE SOLUTIONS

Nitriles serve as special 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.

Nitriles for agrochemicals

NITRALZ® One Source – INNOVATIVE SOLUTIONS

Crops are exposed to different kinds of threats worldwide. The agro industry provides various solutions to protect them.

For the production of such agricultural products, like special fungicides, insecticides and herbicides nitriles are used.

In many innovations of agricultural products, our nitriles serve as an important component.

 

NITRALZ® stands for high quality of aromatic and aliphatic nitriles MADE IN GERMANY.

Our customers benefit from our long experience and our competence in high temperature reactions. We are also proud of our in-house catalyst development.

We guarantee high quality, efficient technologies, innovative processes and a high standard to service our partners.

 

We offer you a broad product portfolio of various intermediates for agrochemicals.

Here a few examples of our commercial nitriles mainly used in the agrochemical sector:

NITRALZ® CAS No. application area examples end product examples specification
Benzonitrile 100-47-0 herbicide, solvent Fenclorim ≥ 99,6%
n-Butyronitrile 109-74-0 solvent   ≥ 99,5%

Nitriles for HPP & Phthalocyanine Pigments

NITRALZ® One Source – INNOVATIVE SOLUTIONS

High quality nitriles via gas phase technology MADE IN GERMANY:

We offer you a broad product portfolio for the production of your Diketopyrrolopyrrol-Pigments (DPP Pigments).

 

Our NITRALZ® products are used as intermediates for example for the following High Performance Pigments (HPP):

NITRALZ®

 CAS No. used for the production of specification
Benzonitrile 100-47-0 Pigment Red 255 (PR 255) ≥ 99,6%
4-Bromobenzonitrile  623-00-7 orange-red ≥ 99,0%
3-Chlorobenzonitrile 766-84-7 orange-red ≥ 99,0%
4-Chlorobenzonitrile 623-03-0 Pigment Red 254 (PR 254) ≥ 99,5%
o-Phthalodinitrile 91-15-6 Pigment Yellow 139 (PY 139) ≥ 99,5%
o-Phthalodinitrileo-Phthalodinitrile 91-15-6 Pigment Yellow 185 (PY 185)

≥ 99,5%
4-tert.-Butylbenzonitrile 4210-32-6 Pigment Orange 73 (PO 73) ≥ 98,0%
4-Tolunitrile 104-85-8 Pigment Red 272 (PR 272) ≥ 98,5%

 

DPP-Pigments are very resistant against light, weather, solvents, heat and chemicals and so they are suitable for quality formulations.

 

Our o-Phthalodinitrile (OPN) can also be used for the production of Phthalocyanines:

NITRALZ®

 CAS No. used for the production of specification
o-Phthalodinitrile 91-15-6 Phthalocyanine Blue 15 (PB 15) ≥ 99,5%
o-Phthalodinitrile 91-15-6 Phthalocyanine Green 7 (PG 7) ≥ 99,5%
o-Phthalodinitrile 91-15-6 Phthalocyanine Green 36 (PG 36) ≥ 99,5%

 

Our OPN has a very high purity and is characterized by low impurities and metal content.

 

Using OPN instead of the route using phthalic acid anhydride brings the following advantages in producing phthalocyanine pigments:

  • More brighter and brilliant pigments.
  • Only one reaction step is required.
  • Direct synthesis with very little formation of by-products and waste water.
    (The structure of the Phthalocyanine is already preformed in the o-Phthalodinitrile)
  • Economic advantages (– because via the PSA route there is only a yield of around 80% and so many by-products have to be disposed of).

 

We can offer our nitriles in different packaging like cardboard boxes, steel drums and iso-containers.

 

Did you know that …

Some of the aromatic nitriles are used to manufacture organic pigments, diketopyrrolopyrroles (DPPs). They are obtained through the condensation of two molecules of nitrile with dimethyl succinate. Depending on the substitution pattern they create yellow, orange, orange and red color pigments. The pigments are used in automotive paints, to dye plastics, in emulsion paints and others. The best-known is certainly PR 254, Irgazine® Red.

PR 254

This pigment provided for the first time a relatively non-toxic and light-fast alternative to Zinnober Red and to the later Cadmium Red. Its inclusion in an automotive paint for a very special car has given this red pigment its nickname – Ferrari Red.
