The American Chemical Society (ACS) is one of the world's largest scientific societies and a leading source of authoritative scientific information in chemistry. Founded in 1876 and chartered by the U.S. Congress, it supports scientific inquiry across the chemical enterprise and serves chemistry professionals through publishing, education, and career and research programmes. Its technical domains span chemistry, the chemical enterprise, scientific publishing and peer review, and chemical education from kindergarten through graduate school.
Central to its work is a portfolio of more than 85 peer-reviewed journals, produced under a stated emphasis on rigorous review and scientific integrity. Alongside the journals, the society develops educational resources covering K-12 through graduate school, administers research grant programmes and scholarships, and runs career development opportunities for chemistry professionals.
ACS operates through 186 local sections across all 50 U.S. states, 32 technical divisions, and international chapters. Project SEED, its initiative to support underrepresented students in chemistry, reflects a stated commitment to diversity and inclusion. The organisation's industry verticals include the chemical enterprise, scientific research, scientific publishing, education and higher education.
