General description

ACS reagent grade.

Application


  • Spectroscopic and quantum chemical analysis of Isonicotinic acid methyl ester.: Demonstrates the utility of spectroscopic methods combined with quantum chemical calculations, techniques potentially applicable to samples involving DMSO ( Shoba et al., 2015).

  • Modification of gelatin by reaction with 1,6-diisocyanatohexane.: Investigates the chemical modification of proteins, potentially relevant for studies using DMSO as a solvent to facilitate such reactions ( Bertoldo et al., 2007).

  • Characterization of O-acetyl-(4-O-methylglucurono)xylan isolated from birch and beech.: Describes the characterization of natural polymers, where DMSO could be used to dissolve and analyze similar substances ( Teleman et al., 2002).

Ethyl2-acetylamino-7-hydroxy-4-pyridin-3-yl-4H-chromene-3-carboxylate (HFI-419), the benzopyran-based inhibitor of insulin-regulated aminopeptidase (IRAP), has previously been shown to improve spatial working and recognition memory in rodents. However, the mechanism of its cognitive-enhancing effect remains unknown. There is a close correlation between dendritic spine density

Questions

1–2 of 2 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
