For 20 years Chemweb has provided the information chemists need to enhance their research, product development, self-development, education, and/or their businesses in Chemistry and related disciplines. Together with our publishing partners we were able to provide our users with free access to tens of millions of abstracts, as well as featured papers.

Changes in search algorithms resulted in a dramatic decline in traffic and a corresponding drop in revenue. Without the resources necessary to maintain the highest quality content we have made the difficult decision to close the site.

Our thanks and gratitude to our users and publishers for your support over these many years.
