One site speciallity is the structure and naming of organic compounds. The site is regularly added to and has now just been recognised by NGFL, Becta/Ferl link page and the BBC secondary schools science links page in the UK.
• Handbook of Chemistry and Physics - CHEMnetBASE is an informational Web site provided by the chemical reference publisher Chapman & Hall / CRC. Although some resources on the site are for subscribers only, the Handbook of Chemistry and Physics is available to anyone.
• i-mass.com - "i-mass.com is a comprehensive web site dedicated to the scientific discipline of mass spectrometry and the concept of mass. This easy to use and navigate site emphasizes the international nature of the field, features monthly articles and journal highlights, and contains essential links to journals, features and WWW tools on every i-mass.com page. The site contains career and conference information, historical perspectives and guides as well as links to mass spectrometry research laboratories, discussion groups, societies and manufacturers worldwide."
• Material Safety Data Sheets On the Internet - Material Safety Data Sheets (MSDS) are an invaluable information source for those working with dangerous substances such as chemicals. One problem often encountered, though, is having access to the sheet when needed; that's where the aptly named Web site, Where to Find Material Safety Data Sheets On the Internet, comes in. The site is provided by Interactive Learning Paradigms Incorporated and compiles around 100 links to free MSDS. The pages are categorized into general sites, government and nonprofit agencies, chemical manufacturers and suppliers, pesticides, and miscellaneous sites -- each with a brief description.
