Merck KGaA, Darmstadt, Germany is a leading science and technology company for innovative and top-quality high-tech products in healthcare, life science and performance materials.
Founded in 1668 in Darmstadt, Merck KGaA, Darmstadt, Germany is the world’s oldest pharmaceutical and chemical company. The success of its export business to the United States led in 1890 to the establishment of a branch in New York, which gave rise to our subsidiary Merck & Co. in 1891. That subsidiary was expropriated by the U.S. government and became an independent company at the end of World War I. Merck KGaA, Darmstadt, Germany and Merck & Co. have been separate companies ever since.
As a result, today there are two different, unaffiliated companies that use the name MERCK. Merck KGaA, Darmstadt, Germany, which operates this website, holds the global rights to the name and the trademark “Merck,” with the exception of the United States and Canada, where the company uses the firm name “Merck KGaA, Darmstadt, Germany,” and also operates as EMD Serono in the biopharmaceuticals business, as MilliporeSigma in the life science business, and as EMD Performance Materials in the materials business.
Merck & Co., Inc., from Kenilworth N.J., USA is not affiliated with or related to Merck KGaA, Darmstadt, Germany. Merck & Co. holds the rights to the trademark MERCK in the United States and Canada but cannot use that trademark in the rest of the world. Merck KGaA, Darmstadt, Germany, owns the trademark MERCK internationally (other than in the U.S. and Canada). To reflect this and to avoid any confusion, publications on this webpage slightly deviate from the otherwise identical versions accessible outside the United States and Canada as certain items such as the logos have been substituted or modified, for instance by referring to “Merck KGaA, Darmstadt, Germany” instead of “Merck” alone.
Our life science business MilliporeSigma provides technologies, tools and solutions that enable our customers to achieve success in the areas of life science research and biotech and pharmaceutical manufacturing.
