AlzChem – your reliable and experienced source for p-Chlorobenzonitrile

AlzChem manufactures the product 4-Chlorobenzonitrile (p-CBN) in its production plant in Trostberg (Southern Germany). We have registered the product 4-CBN according to the REACH regulations.

As manufacturer of a wide range of aromatic and aliphatic nitriles, we are a competent and reliable European source for various types of nitriles such as 4-Chlorobenzonitrile.

As one of the last remaining producers of nitriles in Europe, the product 4-Chlorobenzonitrile is one of our core products.

With high temperature distillation we achieve the highest quality and purity of our 4-CBN – made in Germany, also known under the brand name NITRALZ®.

With a purity of min. 99.5% it is available as solidified melt (packaging: iso-containers or 200 kg steel drums) and as flakes (packaging: 25 kg cardboard boxes).

4-Chlorobenzonitrile is mainly used as raw material for the production of high-performance pigments (HPPs), such as for the red pigment PR 254 and as intermediate for agrochemicals. In the pharmaceutical sector, 4-Chlorobenzonitrile has an important role as a building block for various active pharmaceutical ingredients (APIs).
