This is BASF's website. They're a chemical company based out of Germany. I wonder if they had similar beginnings as IG Farben/Bayer: https://www.basf.com/us/en.html

In 1925, BASF merged with Bayer, Hoechst and three other companies to form I.G. Farbenindustrie AG. Between 1933 and 1945, I.G. Farben played a central role in the Nazi economy

PDF : Report of the Investigation of I. G. Farbenindustrie A. G. Prepared by Division of Investigation of Cartels and External Assets Office of Military Government, U. S. (Germany) November, 1945 excerpts:

A basic purpose of this investigation was to uncover as much information as possible concerning the nature and location of the far-flung and carefully concealed external assets of I. G. Farben. The investigation was, therefore, an important phase f the program adopted by the Allied Powers at Potsdam to strip Germany of all of her external assets in the interest of future world security and to use such assets for the relief and rehabilitation of countries devastated by Germany in her attempt at world conquest.... The report describes the methods used by I. G. Farben in penetrating into the economic life of foreign countries as a means of achieving world domination of the chemical industry, as well as the cloaking devices designed to conceal Farben’s external investments and interests.

I. G. Farben, nominally a private business enterprise, has been and is, in fact, a colossal empire serving the German State as one of the principal industrial cores around which successive German drives for world conquest have been organized. With a net worth of RM 6 billions at the very minimum, its domestic participations comprise over 380 other German firms. Its factories, power installations and mines are scattered all over Germany. It owns its own lignite and bituminous coal mines, electric power plants, coke ovens, magnesite, gypsum and salt mines. Its foreign participations, both admitted and concealed, number over 500 firms valued at a minimum of RM 1 billion. Its holding companies and plants blanket Europe; and its house banks, research firms and patent offices are clustered around every important commercial and industrial center in both hemispheres. In addition to its numerous foreign subsidiaries, I. G.’s world-wide affiliations included hundreds of separate non-German concerns and ranged over a score of industries. Its cartel agreements numbered over 2,000 and included such major industrial concerns as Standard Oil (New Jersey), the Aluminum Company of America, E. I. DuPont de Nemours, Ethyl Export Corporation, Imperial Chemical Industries (Great Britain), the Dow Chemical Company, Rohm and Haas, Etablissments Kuhlmann (France) and the Mitsui interests of Japan.

This report does not pretend to tell the complete story. In anticipation of Allied victory, thousands of Farben’s secrets went underground along with other German resources to lay the foundation for World War III; and thousands of its important files were, according to the testimony of its responsible officials, destroyed just prior to the advent of the Allied troops.

In 1938 the German government, dissatisfied with the progress made in the development and production of poison gases, called upon Farben to handle the problem. New I. G. plants for the production of these gases swung into operation and eventually, as indicated above, I. G. achieved 95 percent of the total production of poison gases. By order of the German Government many of these plants were completely destroyed before the occupation by the Russians; and all “fore and end products” were destroyed. But at least one of these terrible secrets which the Germans hoped to save for the next war has been uncovered. This investigation had disclosed that an I. G. Farben official at Wuppertal-Elberfeld developed the deadliest poison gas in the world. This gas, unknown to the military authorities of the Allied Nations, could have penetrated any gas mask in existence. I. G. originally carried out its poison gas experiments on monkeys; later on human beings. For the latter purpose, inmates of concentration camps were selected, and I. G. Farben officials, concerned only with creating weapons capable of assuring German world conquest, were unmoved by this use of human guinea pigs. Dr. ter Meer, one of I. G.’s leading scientists, who will be described in detail at a later point, justified the experiment not only on the grounds that the inmates of concentration camps would have been killed anyway by the Nazis, but also on the grounds that the experiments had a humanitarian aspect in that the lives of countless “Aryan” workers were saved thereby. Needless to say, these gases were not only used on helpless people during the stage of experimentation, but were later used to exterminate whole groups in concentration camps such as Auschwitz.
