We also subscribe to the Chemical Abstracts database called SciFinder Scholar. Look up the substance by using the “Substance Identifier” feature. On the results page of a substance search, view the option “Get Commercial Sources”--find the manufacturer then go to that commercial supplier’s website. Suppliers are often willing to give price data.
