The International Union of Pure and Applied Chemistry (IUPAC), established in 1919, is the international body that represents chemistry and related sciences and technologies. IUPAC currently has 44 National Adhering Organizations and 21 Associate National Adhering Organizations.
IUPAC promotes continuing cooperation among the chemists of its Member Countries; studies topics of international importance to chemistry requiring standardization or codification; cooperates with other international organizations in topics of a chemical nature; and contributes to the advancement and understanding of pure and applied chemistry in all aspects. IUPAC primarily pursues these objectives through the contributions of over 1000 volunteer chemists. Nearly 5000 chemists are enrolled in the Affiliate Member Programme, which provides a virtual channel of global communication.
IUPAC is recognized as the international authority on chemical nomenclature, terminology, symbols, units, atomic weights and related topics. Its reports and recommendations on these matters are often accepted as definitive and form the basis for drafting regulations relating to chemical manufacturing, international commerce, and matters relevant to food, health and the environment.
IUPAC conducts a biennial Congress (Ottawa 2003, Beijing 2005) aimed toward frontiers in the chemical sciences, and sponsors numerous symposia in specialized topics in chemistry. IUPAC publications include a journal, Pure and Applied Chemistry, and the news magazine Chemistry International. The IUPAC website is a portal of information for all chemists.
Through CHEMRAWN Conferences (CHEMical Research Applied to World Needs) and subsequent actions, IUPAC addresses issues within society for which chemical research is important. A high-level International Chemistry Council, jointly appointed by IUPAC and UNESCO, provides overall guidance for programmes directed toward developing countries.
IUPAC maintains a professionally staffed Secretariat headed by an Executive Director in Research Triangle Park, North Carolina, USA.
