I am Harald, Dr. (phd) of chemistry, in my thesis I used 2-pyridone as a catalyst for aminolysis reaction. At that time I was working at the Ludwig Maximilians University. I was employed at the Max Planck Institute for Solar System Research working on the GC-MS of the Rosalind Franklin (rover), now I work for OHB SE.
