The Executive Committee of the Division of Organic Chemistry of the American Chemical Society and the University of Minnesota Department of Chemistry invite you to attend the 50^th National Organic Chemistry Symposium (NOS). This biennial event will be held from Sunday July 25 to Thursday July 29, 2025 at the University of Minnesota in Minneapolis, Minnesota. You can find some of the latest information on the upcoming NOS on Social Media #NOS2027.

The 50^th NOS will be chaired by Mingji Dai (Emory University) and Alex Grenning (University of Minnesota). The NOS 2027 location was selected in part based on the strength and enthusiasm of the local organizers.

Several NOS lectures from the 2013–2025 are currently available to Organic Division members. See the Organic Division’s Main web site. The program books from all previous NOS are available from the NOS History page .

The DOC is committed to fighting implicit bias. Hate has no place in the DOC, the ACS, in science, or anywhere. The DOC has accordingly adopted an Anti-Harassment Policy.

The National Organic Chemistry Symposium is the premier event sponsored by the Division of Organic Chemistry to highlight recent advances in organic chemistry, and provides a breadth of programming and opportunities that you won’t want to miss. Please plan to join us in 2027!
