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

应用
- 通过SmI2诱导的吲哚衍生物的环化生成的苯环吡咯里西啶和吲哚里西啶。[1]
- 通过不对称Reformatsky型反应合成手性4-取代2-恶唑烷酮和5,5-二取代恶唑烷酮。[2]
- γ通过羰游基-烯烃偶联反应生成-氨烷基取代γ-丁内酯。[3]
还可用于：
- 使用SmI2/H2O/胺混合物还原共轭双键和三键成烯烃。[4]
- 通过SmI2/H2O/Et3N将β-羟基酮转化成1,3-二醇。[5]
- 使用SmI2/H2O试剂系统选择性还原六元内酯成相应的二醇/三醇。[6]
SmI2是一种有效的单电子还原剂，用于在温和条件下促进酮烯烃、羰游基芳香基环化和频哪醇偶联反应。[7][8][9]通常，分子内[10]和分子间偶联[10]都以较高的立体选择性方式进行。此外，它还用于合成新型芳氧钐/环戊二烯配合物。[11][12]

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