General description

2,2′-(Ethylenedioxy)diethanethiol (EDT) is a dithiol based cross-linker that can be used for thiolene photopolymerization and to obtain crosslinked polymeric films.[1][2]
3,6-dioxa-1,8-octanedithiol is non volatile in nature.

Application

3,6-dioxa-1,8-octanedithiol (DODT) was used for cleaving peptides in the study to develop synthetic peptide serology to treat chronic chagas disease.[3] DODT may be used to develop non-malodorous scavenger in Fmoc-based peptide synthesis.[4]
EDT can be crosslinked with unsaturated olive oil to form a photoinduced eco-friendly film through renewable sources.[2] It can be used in the synthesis of bioanode for the fabrication of a biofuel cell (BFC) for glucose sensing application.[5] It may also be used for other applications such as improving the optical properties of gold nanoclusters (AuNCs)[6] and the development of bio-mediated synthetic polyester.[7]

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.
