Welcome to IUPAC | International Union of Pure and Applied Chemistry. We are turning 100! The content of this special edition website is tailored around events and activities surrounding our Centenary anniversary  celebration!

There will be IUPAC Stories related to the Essential Tools created by the work of IUPAC throughout the years. A Periodic Table of Younger Chemists is seeking nominations. Take a look around, and see where you and your organizations may be interested in getting involved, submitting nominations, and preparing for a Global Periodic Table Challenge happening in 2019!
