General description

Chloroform is a volatile chlorinated organic solvent whose vapors have a narcotic effect. Due to its light sensitivity, it may undergo degradation with time. This can be suppressed by adding ethanol as a stabilizer. The addition will increase the polarity of the solvent and potentially impact certain applications.

Application

Chloroform has been used as a solvent for dissolving lipids and also as a cleansing agent. It may also be used in solvent extraction process and also for recrystallization.

Questions

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
