IUPAC will celebrate 100 years holding its 50th General Assembly and 47th World Congress in Paris, France, along with a dedicated session and exhibition and gallery of IUPAC Presidents.

Starting in July 2018, access to Chemistry International will be restricted to IUPAC Members and Affiliate Members. Authentication will require that you LOGIN for free access to CI.
The default distribution of CI is now digital and those who wish to receive a print copy are invited to subscribe.

LOGIN also to review your profile and mailing address, and to reaffirm what personal information IUPAC can share publicly.

With the IUPAC Poster Prize program, National Adhering Organizations and eligible IUPAC-endorsed conferences can encourage interest in conferences among young chemists.
