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.

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

The International Union of Pure and Applied Chemistry (IUPAC) is the world authority on digital standards in chemistry; chemical nomenclature and terminology, including the naming of new elements in the periodic table; on standardized methods for measurement; and on atomic weights.

By virtue of its work in relation with the chemical elements, IUPAC can dispense a periodic table that is up-to-date. IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input. In particular, IUPAC is directly involved in the following:

2007年4月18日 · IUPAC is well known for publishing definitive and up-to-date data on atomic weights and isotopic abundances. It also publishes a wide variety of other chemical data of immense value to chemists and chemical engineers.

IUPAC is the universally-recognized authority on chemical nomenclature and terminology and two IUPAC bodies take leading roles in this activity: Division VIII – Chemical Nomenclature and Structure Representation and the Interdivisional Committee on Terminology, Nomenclature, and …

IUPAC was formed in 1919 by chemists from industry and academia, who recognized the need for international standardization in chemistry. The standardization of weights, measures, names and symbols is essential to the well being and continued success of the scientific enterprise and to the smooth development and growth of international trade and ...

Welcome to the new interactive version of IUPAC Compendium of Chemical Terminology, informally known as the "Gold Book". On these pages you will find a new browsable, version of this publication. Start by: browsing the alphabetical …

IUPAC Recommendations are the output of IUPAC Projects or other studies on nomenclature, symbols, terminology, or conventions, and their purpose is to recommend unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields

The universal adoption of an agreed nomenclature is a key tool for efficient communication in the chemical sciences, in industry and for regulations associated with import/export or health and safety. IUPAC provides recommendations on many aspects of nomenclature.
