Official website includes information regarding membership, job opportunities, news, contact and scholarly communication. Fun features include the Molecule of the Week and an excellent animated Periodic Table (requires Shockwave plugin).

PubChem is an open chemistry database at the National Institutes of Health (NIH). Since the launch in 2004, PubChem has become a key chemical information resource for scientists, students, and the general public. PubChem mostly contains small molecules, but also larger molecules such as nucleotides, carbohydrates, lipids, peptides, and chemically-modified macromolecules. They also collect information on chemical structures, identifiers, chemical and physical properties, biological activities, patents, health, safety, toxicity data, and many others.

This site is from MIT, and has many different chemistry-related tools. For quick reference.

Contains definitions of chemical terms. Sections include: chemical reactions; experimental chemistry; geology; inorganic chemistry; mineralogy; organic chemistry; petrology; and quantum chemistry. Subject hierarchy, alphabetical index and search engine allow quick and easy browsing and searching. Part of World of Science, a "budding online encyclopedia" being assembled by Internet encyclopedist Eric Weisstein.

A very long list of links to free, online chemistry resources in the following categories: Chemistry Journals; Chemistry Overviews; Periodic Tables and Databases; Chemical and Biochemical Databases; Chemistry 1st and 2nd Year Courses, Tutorials, and Movies; Analytical Chemistry Courses, Tutorials, and Movies; Chemistry by Subject Courses, Tutorials, and Movies.

A collection of freely available digital resources in the sciences, sponsored by the National Science Foundation.

Created by Seed Media Group, this online community includes more than 80 science experts blogging about their fields. Covering everything from life and physical science and medicine to technology and science topics in politics, this is a great resource for anyone studying the scientific world.

Part research database, part interactive tool, this website provides an introduction to different aspects of chemistry, focusing on students.
