IUPAC Centenary

Plan to celebrate and get involved!
In 2019, IUPAC will celebrate 100 years of successes.
The celebrations will not only recognize the successes of IUPAC’s first one hundred years, but also look to the future of what this international community of chemists, working closely together, can continue to contribute in meeting the world’s needs through chemical research.
