Sharing your passion for chemistry, connecting with one of the world’s largest scientific societies, and advancing your career in this ever-changing global economy.

ACS organizes two national expositions each year in conjunction with our national meetings, each attracting an estimated 11,000-14,000 chemists, chemical engineers, academicians, graduate and postdoctoral students, and other professionals.

Our National Meetings offer scientific professionals a legitimate platform to present, publish, discuss and exhibit the most exciting research discoveries and technologies in chemistry and its related disciplines. Furthermore, our national meetings facilitate networking opportunities, career development and placement, and provide companies an opportunity to exhibit products and services to a targeted audience.
