A legacy of excellence

In 1904, John Townsend Baker founded the J.T.Baker Chemical Company with a mission to produce chemicals of the "highest degree of purity commercially available." As the first to include lab results listing trace impurity levels on labels, J.T.Baker chemistries quickly established a reputation for quality, data transparency and collaboration. Since that time, the J.T.Baker brand has stood for excellence from the laboratory to full-scale production, driving innovation and advancing science around the world.
