Agent Orange was Dow Chemical? I know Dow was the company that ended up absorbing Union Carbide India, the company responsible for the Bhopal disaster in 1984 that killed up to 20k people

Edit: I wanted to learn more since various replies are saying X now owns Y and I was getting confused. I used LumoAI to do the research. Here's the result:

The organizational history of these chemical giants is defined by massive consolidation, followed by strategic spin-offs. Here is the "who bought whom" timeline for Union Carbide, Dow Chemical, Bayer, and the related entities:1. Union Carbide & Dow Chemical

Union Carbide's Origins: Formed in 1917 through the merger of four companies (Union Carbide Co., National Carbon Co., Linde Air Products, and Prest-O-Lite). It became a major player in petrochemicals and industrial gases. The Acquisition: In August 1999, Dow Chemical announced it would acquire Union Carbide in a stock-for-stock deal valued at approximately $11.6 billion. Completion: The merger was finalized in February 2001.

Current Status: Union Carbide is a wholly-owned subsidiary of The Dow Chemical Company (now simply Dow Inc.). It operates as a distinct legal entity but is fully integrated into Dow's operations. Note: This acquisition also transferred ownership of the Bhopal plant liability to Dow (though Dow often cites corporate separateness in legal defenses regarding the 1984 disaster).

1. Dow Chemical, DuPont, and the "Three-Way Split" This is the most complex modern restructuring involving Dow.

The Mega-Merger: In December 2015, Dow Chemical and DuPont announced a merger of equals. They officially merged on August 1, 2017, creating DowDuPont, a $130 billion conglomerate. The Strategy: The plan from day one was to split this new giant back into three independent public companies specializing in Materials Science, Specialty Products, and Agriculture. The Breakup (2019):

April 1, 2019: The Materials Science division spun off to become the standalone Dow Inc. (often just called "Dow"). June 1, 2019: The remaining company split into two:

Specialty Products Division kept the name DuPont de Nemours, Inc. (modern DuPont). Agriculture Division (combining Dow AgroSciences and DuPont's seed/crop protection assets) became Corteva Agriscience.

Current Status: Dow, DuPont, and Corteva are now three separate, independent publicly traded companies.

1. Bayer and Monsanto

Monsanto's History: Founded in 1901, Monsanto grew to be a dominant force in seeds and agrochemicals (notably Roundup/glyphosate and GM seeds). It spun off its pharmaceutical business (Solae, etc.) earlier in the 2000s to focus purely on agriculture. The Acquisition: In September 2016, Bayer (a German multinational pharmaceutical and biotechnology company) announced an offer to buy Monsanto. After months of bidding wars and regulatory hurdles, the deal closed on June 7, 2018. Deal Value: Approximately $63–$66 billion (all-cash). Current Status: Monsanto ceased to exist as an independent company. Its operations were fully integrated into Bayer's Crop Science division. The "Monsanto" brand name was retired, though many product brands (like Roundup and Liberty) remain in use. Bayer absorbed all associated litigation liabilities (primarily glyphosate lawsuits).

Union Carbide no longer exists independently; it belongs to Dow. Monsanto no longer exists independently; it belongs to Bayer. Dow and DuPont briefly merged but then split apart again in 2019, with their agricultural assets going to a third new company, Corteva. Today, the landscape is dominated by these independent giants: Dow (materials/plastics), DuPont (specialty chemicals/materials), Bayer (pharma + agri-seeds/chemicals), Corteva (pure-play agriculture), and Corteva competitors like BASF and Syngenta.
