The International Union of Pure and Applied Chemistry (Iupac) will be based between Malaga, Spain and Rome, Italy, from summer 2026 following a two-year-long search for a new home. The organisation, which acts as chemistry’s governing body and custodian of the periodic table, announced in June 2024 it was planning to leave its current home at Research Triangle Park, North Carolina, where it has been based since 1997.
