Application

Magnesium sulfate (MgSO4) has been used as a medium supplement in the M63 minimal medium for bacteria.[1]
Anhydrous MgSO4 plays the role of a drying agent in the synthesis of 3,6-bis(3,4′-dihexyl-2,2′-bithiophen-5-yl)-1,2,4,5-tetrazine[2] and organic molecules having an A–D–A (D = donor, A = acceptor) structure.[3]
It may be used as an additional reagent in the synthesis of t-butyl esters and ethers by reacting carboxylic acid or alcohol and t-butanol in the presence of catalytic sulfuric acid.[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.

  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.
