Koei Chemical

Koei Chemical is a Japan-based publicly traded specialty chemicals manufacturer that produces nitrogen-containing compounds and other chemical products, including pyridines, pyrazines, amines, formalin products, and ionic liquids. The company supplies materials used across pharmaceuticals, agrochemicals, resins, electronics, and other industrial applications, and it also supports custom synthesis and specialty-product manufacturing. Within healthcare, Koei Chemical appears to participate primarily as an upstream supplier of small-molecule intermediates and raw materials for the pharmaceutical industry rather than as a therapeutic drug developer. The company operates from Tokyo with manufacturing and research functions in Chiba and maintains additional business presence in Osaka. It has been in operation since 1917 and remains part of the Sumitomo Chemical group while listed on the Tokyo Stock Exchange.
