ACS is a congressionally chartered independent membership organization which represents professionals at all degree levels and in all fields of chemistry and sciences that involve chemistry.

With more than 154,000 members, the American Chemical Society (ACS) is the world’s largest scientific society and one of the world’s leading sources of authoritative scientific information. A nonprofit organization, chartered by Congress, ACS is at the forefront of the evolving worldwide chemical enterprise and the premier professional home for chemists, chemical engineers and related professions around the globe.
Our Mission and Vision

We are dynamic and visionary, committed to “Improving people’s lives through the transforming power of chemistry.”

This vision ─ developed and adopted by the ACS Board of Directors after broad consultation with the membership ─ fully complements the ACS Mission statement, which is “to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and its people.” Together, these two statements represent our ultimate reason for being and provide a strategic framework for our efforts.

What We Do

The Society publishes numerous scientific journals and databases, convenes major research conferences and provides educational, science policy and career programs in chemistry. We also give more than $22 million every year in grants for basic research in petroleum and related fields.

We also play a leadership role in educating and communicating with public policy makers and the general public about the importance of chemistry in our lives. This includes identifying new solutions, improving public health, protecting the environment and contributing to the economy.
