The two young groups Sanofi and Synthélabo merged in May 1999 to create a major new pharmaceutical player. Sanofi dates back to 1973 and Synthélabo to 1970. In December 1999, Rhône-Poulenc and Hoechst Marion Roussel formalized their merger with the creation of the Franco-German group Aventis, one of the world’s largest pharmaceutical companies. In August 2004, Sanofi-Synthelabo acquired Aventis. The takeover was finalized on December 31 of that year, giving birth to sanofi-aventis.

On May 6, 2011, sanofi-aventis simplified its name to Sanofi. Sanofi  operates in over 100 countries throughout the world.
