Descripción general

Dimethyl disulfide (DMDS) is an organic dialkyl disulfide. It is one of the odorous compounds found on the working face of typical municipal solid waste landfill in China.[1] DMDS forms adducts with mono-unsaturated acetates by addition across carbon-carbon double bonds. These adducts are useful to locate the of double bonds in long-chain mono-unsaturated acetates.[2] Adsorption of DMDS on Au(111) surface has been investigated by the density functional theory (DFT) within a generalized gradient approximation and experimental high-resolution electron energy loss spectroscopy (HREELS) techniques.[3]

Aplicación

Dimethyl disulfide (DMDS) may be used to derivatize alkenes for the determination of position of double bond by MS.[2] It may also be used to determine the location of the double-bond position of monounsaturated fatty acids in Campylobacter cryaerophila by combined GC-MS analysis.[4]

Questions

1–2 of 2 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.
