Hoechst AG (German pronunciation: [ˈhøːçst]) was a German chemicals, later life sciences, company that became Aventis Deutschland after its merger with France's Rhône-Poulenc S.A. in 1999. With the new company's 2004 merger with Sanofi-Synthélabo, it became a subsidiary of the resulting Sanofi-Aventis pharmaceuticals group.
