The International Union of Pure and Applied Chemistry (IUPAC) is the world authority on chemical nomenclature and terminology, including the naming of new elements in the periodic table; on standardized methods for measurement; and on atomic weights, and many other critically-evaluated data.

A neutral and objective scientific organization, IUPAC was established in 1919 by academic and industrial chemists who shared a common goal – to unite a fragmented, global chemistry community for the advancement of the chemical sciences via collaboration and the free exchange of scientific information. Throughout its long history IUPAC has fulfilled that goal through the creation of a common language and the standardization of processes and procedures.

But IUPAC is about much more than nomenclature and the naming of elements. We are a leader in the provision of objective scientific expertise for the resolution of critical global issues that involve every aspect of chemistry, all of which have societal impact. Our scientific work is conducted largely through a formal project system, in which proposals from chemists around the world are peer-reviewed and, if meritorious, are approved and supported. In addition, IUPAC is involved in a wide range of diverse activities that ultimately impact both the chemical profession and society as a whole. 

For almost a century IUPAC has contributed to the diverse and interdisciplinary field that is chemistry. We are the catalyst that unites chemists worldwide and we fulfill our mission by fostering sustainable development, providing a common language for chemistry, and advocating the free exchange of scientific information.

We are IUPAC – International and Unique, advancing Pure and Applied Chemistry worldwide!


Founded in 1903, the KNCV is the professional association of chemists, life scientists and process technologists in the Netherlands.

The Royal Netherlands Chemical Society (KNCV) is the largest chemical professional association in the Netherlands. Our member base consists of people with a shared passion for molecules and includes chemists, life scientists, process technologists and (bio-)molecular scientists. Our 8,500 members, who work hard to bring the variety and richness of the molecular field to life, operate in business, education and government or study at universities or institutions of higher education in the Netherlands.

The KNCV is the representative of chemistry, life sciences and process technology in the Netherlands – three disciplines that contribute significantly to our social and community welfare. Alongside representation and networking activities, the KNCV also contributes to presenting a correct image of chemistry by providing accurate and proper coverage of chemistry.

The molecular sector is important for the Netherlands, both from an economic perspective and because of its high international reputation. A quarter of the Dutch research and development expenses are related to the molecular sciences.

The KNCV also has a strong presence in the European arena via our role in EuCheMS, the umbrella organisation for 47 European chemical societies. On an international level, the KNCV is active in various divisions of the International Union of Pure and Applied Chemistry (IUPAC).

The molecular sector employs responsible and engaged people who are passionate about developing products that make a significant contribution to the world.
Together, they form the KNCV.


The Dutch Research Council (NWO) is one of the most important science funding bodies in the Netherlands and realizes quality and innovation in science. Each year, NWO invests almost 1 billion euros in curiosity-driven research, research related to societal challenges and research infrastructure.

NWO selects and funds research proposals based on recommendations from expert scientists and other experts in the Netherlands and abroad. NWO encourages national and international collaboration, invests in large research facilities, facilitates knowledge utilisation and manages research institutes. NWO funds more than 7200 research projects at universities and knowledge institutions.
