Chemdex.com
(重定向自Chemdex)
Chemdex.com was one of the first online business-to-business (B2B) e-commerce companies (called itself the leading life science e-commerce marketplace). Based in the United States, Chemdex provided an online marketplace for sales of chemicals, enzymes, lab equipment, biotech products like peptides, and many types of chemical reagents. Once an IPO darling of Wall Street, it was never profitable and it became one of many companies destroyed in the dot-com crash of the early 2000s.
