Chemical Samples Recycling: The MDPI Samples Preservation and Exchange Project

  • S.-K. Lin


Over the years, chemists have been known to make a significant contribution to science, and to generate new chemical substances as a result of their professional activities. Over 20 million compounds have been recorded in the literature, however, because of their use in chemical processes and their disposal in waste products, only a smaller number of these compounds are available for furture use. Therefore, there is a tremendous loss of molecular diversity and chemical heritage. Reproduction of samples, if successful, is expensive and time-consuming. It may also contribute to a substantial damage to the environment. Chemical sample archives are priceless resources that can tremendously facilitate and speed-up discovery of new drugs, and new compounds, as well as the development of many other chemical products, with industrial, pharmaceutical, agricultural, educational, and research applications. The Molecular Diversity Preservation International (MDPI) project has been successful in carrying out worldwide collections/deposits, exchanges, and "recycling" of a significant number of chemical samples.
