He initially trained and worked as a pharmacist, from 1841 he studied sciences at the University of Berlin. He earned his PhD at Berlin in 1844 under Heinrich Rose, and two years later, obtained his habilitation in chemistry. In 1850 he became an associate professor at the University of Halle, where in 1855 he attained a full professorship.[1] He was one of six founding members of the Deutsche Physikalische Gesellschaft and the only chemist.

At Halle, Heintz supervised Johannes Wislicenus's Ph.D. work, although Wislicenus' pro forma advisor at Zurich was Georg Karl Andreas Städeler.[2] With Christoph Gottfried Giebel, he was editor of the Zeitschrift für Naturwissenschaften.[3]

In 1853 he analyzed margaric acid as simply a combination of stearic acid and palmitic acid.[4] He also conducted analysis of uric acid in urea, created methods for the analysis of nitrogen in organic compounds, and studied chemical reactions of chloroacetic acid and the reaction of acetone with amines. In addition he performed chemical investigations of uranium, bismuth, caesium, rubidium and metal phosphates.[5][1]

The mineral heintzite is named for him.
