This page contains a list of websites for suppliers of laboratory and fine chemicals. It is not intended to be comprehensive; it is primarily U.S. companies, and does not include suppliers of bulk or industrial-scale chemicals. If you have suggestions for additional listings, please send them to the page owner.
In addition to their usefulness for those seeking to obtain price or ordering information, many of these websites (as noted) also provide property information on the chemicals supplied, and so can be of use to the student or researcher seeking basic chemical data.
