应用

硫酸镁（MgSO4）已用作M63细菌基本培养基中的培养基补充剂。[1]
无水MgSO4在3，6-双（3，4′-二己基-2，2′-联噻吩-5-基）-1，2，4，5-四嗪[2]和有机分子的合成中起干燥的作用，有机分子具有A-D-A（D=供体，a=受体）结构。[3]
它可以在催化硫酸的存在下，通过使羧酸或醇与叔丁醇反应，在叔丁酯和醚的合成中用作附加试剂。[4]

Questions

1–3 of 3 Questions  

  1. 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

  2. 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

  3. what is the particle size of this granular one (208094-500G)? Is it easy to be filtered?

    1 answer

    1. Particle size for this item is not an assayed property. Unfortunately, this information is not available for this specific product. It is not known if this item can be easily filtered. Filtration rate is dependent upon several properties, such as filter size, membrane size, pressure used, viscosity, etc.
