Carl Mannich


Carl Ulrich Franz Mannich was a German chemist. From 1927 to 1943 he was professor for pharmaceutical chemistry at the University of Berlin. His areas of expertise were keto bases, alcohol bases, derivatives of piperidine, papaverine, lactones and also Digitalis-glycosides.
The Mannich reaction was named after his discovery of the mechanism in 1912.

Biography

Life

Mannich attended high school in Weimar and later on in Berlin where he left before graduating, taking an internship at a pharmacy instead. From 1898, he studied in Marburg and Berlin and received his doctorate in 1903 in Basel. In 1905, he completed the matriculation examination for the University of Berlin and passed the state examination for food chemistry. He completed his studies at the University of Berlin in 1910 after which he was appointed as an extraordinary professor. Mannich became an extraordinary professor for Pharmaceutical Chemistry in Göttingen from 1911 to 1917, and went to Frankfurt in 1920. Between 1927 and 1943 Mannich was Professor of Pharmaceutical Chemistry at the University of Berlin. In the years between 1932 and 1934 he was President of the “Deutsche Pharmazeutische Gesellschaft ”. In the winter semester 1946/1947, he took over the Chair of Pharmaceutical Chemistry at TH Karlsruhe.

Scientific life

Mannich is well known for his discovery of a special form of amino alkylation which was named after him: the Mannich reaction. Using this synthetic method he was able to produce substances which until then were otherwise difficult to access like 1,3 Ketamine. In 1912 Mannich was able to describe the first synthetical morphine glucoside. He also completed a series of works in 1917 about the opium alkaloids and gave a method for the production of pure opium extracts. Mannich also developed a method for the determination of morphine content in opium, which allowed for effective dosing without having to use complex physiological individual tests. With his synthesis, he contributed to the determination of the structure of morphine.
Due to the introduction of multiple testing and detection methods, such as methods for polarimetric determination of starch, which for the detection of boric acid in food or the amount of ethanol in alcoholic beverages, the field of applied pharmacy owes Mannich a lot.
