General description

Hexadecane (n-Hexadecane) is an aliphatic long-chain hydrocarbon. It is a reference fuel with the cetane number 100 and is employed in determining the cetane number of diesel fuels. The mechanism of the oxidation of hexadecane in the gas-phase has been described.[1] The density, speed of sound, adiabatic compressibility and compressed liquid density of hexadecane have been determined.[2] The performance of platinum/zeolite catalysts for the hydroisomerization of n-hexadecane has been assessed.[3] The thermal degradation of n-hexadecane forms n-alkanes and 1-alkenes as key products.[4]

Application

Hexadecane has been used as a phase change material (PCM) in the preparation of hexadecane/xGnP (exfoliated graphite nanoplatelet), a composite PCM loaded with xGnP.[5]

Protocols

HDM-PAMPA with the MultiScreen Permeability Filter Plate

Assays that predict passive absorption of orally administered drugs have become increasingly important in the drug discovery process. As previously described by Faller and Kansy such assays provide rapid, low cost and automation friendly methods to measure a compound’s passive permeability.

Questions

1–3 of 3 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

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

    1 answer

    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
