Descrizione generale

The chiral resolution of DL-malic acid by ligand-exchange capillary electrophoresis was studied[1].

Applicazioni

DL-Malic acid (MA) can be used:
  • As a dopant in the ammonium dihydrogen phosphate (ADP) crystal to improve the properties of ADP crystals.[2]
  • To form a water-soluble complex, Nb-MA which can further react with LiCl to form lithium niobate (LiNbO3) powders.[3]
  • As a monomer to synthesize a co-polymer, poly(DL-lactic acid-co-α,β-malic acid) (PLMA) with DL-lactic acid which can be coated over magnetic Fe3O4 nanoparticles after functionalizing with fluorescein isothiocyanate (FITC), to be used as a MRI T2-contrast agent.[4]

1–2 di 2 domande  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 risposta
    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 risposta
    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.
