The most commonly used was Zyklon B, a cyanide-based pesticide. Degesch was a chemical company consortium that manufactured the gas. It was owned 42.5% by IG Farben, 42.5% by Degussa, the rest by another company. Many chemical companies supplied components which went into the gas crystals. Dessauer did the actual manufacturing, the stabilizer came from IG Farben, the warning agent from Schering. Schering-Plough and IG Farben are still in business. US General Eisenhower had his headquarters in the IG Farben building immediately after Germany surrendered. The building had not been bombed. Zyklon B is still manufactured, in Kolin in the Czech Republic, under the tradename Uragan D2, for use against insects and small animals.

Auschwitz III (Monowitz) was a chemicals plant built and owned by the German chemicals conglomerate IG-Farben. The original intention was to make synthetic rubber, but the plant only managed to produce various plastics. Initially, prisoners were marched to and from the factory from Auschwitz I, but the long distance meant they arrived tired for their slave labour, so IG-Farben built huts and established a satellite camp.
Around 15,000 Jewish People were killed at Auschwitz III (Monowitz) most of these were killed due to the workings at the IG Farben Factory.
