involved in a well-known legal case, American Cyanamid Co. (No.1) v Ethicon Ltd. (1975), which set the test for awarding an interim injunction in England and Wales and set down what became known to lawyers as the American Cyanamid principles. The American Cyanamid principles are also applied under public procurement law when the high court determines whether to lift the automatic suspension of the power to award a public contract when an application has been made to the court to challenge the lawfulness of a proposed contract award. Acquisition and breakup The company merged with American Home Products (AHP) in 1994. At that time, the purchase price, $9.5 billion, made it the second-largest industrial acquisition in U.S. history to that point. American Home Products eventually changed its name to Wyeth Corporation (one of its subsidiaries), and in 2009 Wyeth merged with Pfizer, becoming a subsidiary of the world's largest pharmaceutical company. After the AHP acquisition, the Cyanamid conglomerate was disassembled over a period of years. The Pigments division was sold to National Lead Company. The Old Spice product line, and some others, were sold to Procter and Gamble. Formica Corporation was taken private in a management buyout, and later went through a series of ownership changes, and is currently owned by Fletcher Building, headquartered in New Zealand. The $1.7 billion agricultural business was sold in 2000 to the German chemical giant BASF, raising BASF agricultural sales to $3.6 billion (1999 pro-forma), making it one of the top three agricultural companies in the world. Most of the chemical businesses of American Cyanamid are now operated by a spun-off successor company known as Cytec. Cytec was acquired by Solvay Group in December 2015 to form the Cytec Solvay Group based in Brussels, Belgium. The American Cyanamid compound in Wayne, New Jersey later served as the headquarters of Toys "R" Us. See also Indiana Harbor Belt Railroad Co. v. American Cyanamid Co.
