Questions

1–6 of 6 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

  3. Where can I find product similar to meso-1,2-Dibromo-1,2-diphenylethane offered by Sigma-Aldrich?

    1 answer

    1. The Sigma-Aldrich website provides many resources for locating products with similar structural characteristics. At the bottom of the product information page for product 106550, there are links to "Related Categories". These links including listings of Sigma-Aldrich products that fall in the same category as meso-1,2-Dibromo-1,2-diphenylethane. Alternatively, Sigma-Aldrich offers an online catalog that provides organized listings of products useful for chemical synthesis, grouped by similar characteristics.

  5. Is Stilbene dibromide, Product 106550, optically active?

    1 answer

    1. Generally, chiral molecules are optically active, rotating polarized light. Meso compounds, such as 106550, are unique in that there are chiral carbons in the molecule yet they are not optically active. meso-1,2-Dibromo-1,2-diphenylethane has chiral carbons that are virtually identical but the arrangement of the groups on this carbon are different; the result of these opposing effects is a net optical rotation of zero.

      Helpful?

  6. In what solvents is Stilbene dibromide, Product 106550, soluble?

    1 answer

    1. Sigma-Aldrich does not currently test this product for solubility in a particular solvent. However, our quality control does solubilize this product with acetonitrile (with sonication) for analysis by HPLC at a concentration of 0.5mg/mL.
