Check the shelves of any research (or mad) scientist and you'll likely find Sigma-Aldrich's chemical products. The company is a leading supplier of chemicals to research laboratories. It has more than 100,000 accounts, including labs involved in government and commercial research, for 250,000 chemical and biochemical and 46,000 equipment products it offers in its Sigma, Aldrich, Fluka and Supelco catalogs. It makes about 114,000 of the products it sells. The business derives revenues from two major areas: Research Chemicals (essentials, specialties, and biotech), and Fine Chemicals (commercial applications). In 2015 the company was acquired by Germany-based pharmaceutical giant Merck for $17 billion.
