The International Union of Pure and Applied Chemistry (IUPAC / ˈ aɪ juː p æ k, ˈ juː-/) is an international federation of National Adhering Organizations working for the advancement of the chemical sciences, especially by developing nomenclature and terminology.

IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.

The International Union of Pure and Applied Chemistry (IUPAC) is an international organisation that represents chemists in individual countries. It governs everything to do with chemicals, elements and new discoveries.

Pure and Applied Chemistry is the official journal for the International Union of Pure and Applied Chemistry (IUPAC). [1] It is published monthly by Walter de Gruyter and contains recommendations and reports, and lectures from symposia.

IUPAC serves the international scientific endeavor in the dual function of a fundamental science and mission-oriented Union. The Union is in a unique position to contribute to the central interdisciplinary chemical sciences.

Die International Union of Pure and Applied Chemistry (IUPAC; deutsch Internationale Union für reine und angewandte Chemie) wurde im Jahr 1919 von Chemikern aus der Industrie und von Universitäten gegründet. Ziel war es, die weltweite Kommunikation der Chemiker untereinander zu ermöglichen und zu fördern. Die IUPAC ist seit langem als die bestimmende Institution …
