In 1823, Friedrich Wöhler completed his medical studies in Germany and traveled to Stockholm to work under the supervision of Berzelius. UreaUrea In 1928, Wöhler observed when evaporating a solution of ammonium cyanate, the formation of large colorless crystals, which did not belong to ammonium cyanate.
The analysis of the same determined that it was urea.
The transformation observed by Wöhler converts an inorganic compound, ammonium cyanate, into an organic compound, urea, isolated from the urine of animals. This experiment was experimental confirmation that organic compounds can also be synthesized in the laboratory.
