COMPENDIUM OF CHEMICAL TERMINOLOGY

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 index (left),
 * using one of the many thematic indexes (left),
 * using the search in the navigation bar (top).

To learn more about this new interactive version see the about page (Updated
July 1st, 2019).



This edition of the IUPAC Gold Book, a compendium of terms drawn from IUPAC
Recommendations and Colour Books, has not been updated in several years. Each
term is correct based upon the source cited in its entry. However, the term's
definition may have since been superseded or may not reflect current chemical
understanding. This site, launched July 2019, is the result of an update to the
technical underpinnings of the Gold Book website to reflect advances in web
technology. IUPAC Divisions will soon review all entries and update the content
as needed. Please send any questions to goldbook@iupac.org.
