Chemical research in toxicology, 4(4), 489-496 (1991-07-01)
4-Ethoxyaniline (p-phenetidine) is oxidized by peroxidases to form several products, one of which is 4-[(4-ethoxyphenyl)imino]-2,5-cyclohexadien-1-one (1). This compound reacts with N-acetylcysteine (NAC) in methanol-phosphate buffers, generating at least four different products. Four major products, 4-[(4-ethoxyphenyl)amino]phenol (2), 3-(N-acetylcystein-S-yl)-4-[(4-ethoxyphenyl)amino]phenol (3), 2,5-bis(N-acetylcystein-S-yl)-4-[(4-ethoxyphenyl)-amino]phenol (4)

The metabolism of p-phenetidine in microsomes from rabbit kidney and the metabolism of acetaminophen and p-phenetidine in human kidney microsomes to protein binding metabolites were examined. Microsomal preparations from rabbit kidney medulla catalyzed the irreversible arachidonic acid-dependent binding of p-[14C]phenetidine

The interaction of N-(4-ethoxyphenyl)p-benzoquinone imine (NEPBQI), a metabolite formed during peroxidase catalyzed metabolism of p-phenetidine, with GSH and its effects in isolated rat hepatocytes were investigated. When reacted with GSH NEPBQI formed both a mono- and a diglutathione conjugate as

Metabolic activation of phenacetin by liver microsomes proceeds via both phenetidine and N-hydroxyphenacetin to direct-acting mutagens, i.e., N-hydroxyphenetidine and p-nitrosophenetole. Five different molecular species of cytochrome P-450 have been purified from liver microsomes of drug-pretreated Wistar rats or Syrian hamsters

Targeted biologic therapies have revolutionised treatment of immune-mediated inflammatory diseases (IMIDs) due to their efficacy, speed of onset and tolerability. The discovery that clinically unrelated conditions, such as rheumatoid arthritis and Crohn's disease, share similar immune dysregulation has led to

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
