What it led to
- Empirical formulae of organic compounds
- Modern teaching laboratory
- Agricultural chemistry and fertilisers
Built on
- Gay-Lussac and Thénard's analysis
- Berzelius's atomic weights
Made possible
- Wöhler synthesis of urea1828
- Isomerism1825-1830
- Radical theory and type theory1837-1853
- Liebig's extract of meat1865
- mineral fertilisers
