Each year IUPAC endorses a large number of independently organized conferences, symposiums and workshops that cover a wide range of specialized topics in chemistry. Endorsement by IUPAC attests to the quality of the scientific program and indicates the host country’s assurance that scientists from all countries may participate. See program details. In addition, the calendar below includes webinars and workshops related to specific IUPAC projects or joint activities with associated organizations.

24th International Conference on Organic Synthesis

We are pleased to announce that the 24th International Conference on Organic Synthesis (24-ICOS) will be held on July 5–10, 2026, in Łódź.

For the very first time, this prestigious biannual IUPAC event comes to Poland – the country by the Vistula River. 

Celebrating the 50th anniversary of the Conference, we aim to continue the success of previous editions by creating an open and global platform for presenting scientific results. Under the ICOS banner, leading experts and young scientists will gather to further push the boundaries of chemistry, discussing topics such as synthetic methodology, catalysis, applied and bioorganic chemistry, chemical biology, the synthesis of natural products, and the chemistry of nano- and functionalized materials.
