Allgemeine Beschreibung

Petroleum ether is the petroleum fraction, consisting of C5 and C6 hydrocarbons (Pentanes and hexanes are the major constituents), commonly used as a laboratory solvent due to its low boiling point and non-polar characteristics.

Anwendung

Petroleum ether can be used as a solvent for extracting:
  • Non-polar compounds from various samples, such as plant materials or organic mixtures.[1]
  • Carotenoids from the marine Thraustochytrium sp. ONC-T18.[2]

Fragen

1-3 von 3 Fragen  

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

    1 Antwort

    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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 Antwort

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. Can this reagent be used for liquid extraction in laboratory settings? My project will be extracting cortisol from blood serum. Will this reagent apply to this?

    1 Antwort

    1. Hormones such as progesterone and cortisol can be extracted by mixing 0.2 mL of plasma with 5 mL of petroleum ether or diethyl ether. So product 320447-1L can be used for the extraction of cortisol from blood serum.
