[formula: see text] 4'-Bromoacetophenone derivatives which upon excitation can generate monophenyl radicals capable of hydrogen atom abstraction were investigated as photoinducible DNA cleaving agents. Pyrrolecarboxamide-conjugated 4'-bromoacetophenones were synthesized, and their DNA cleaving activities and sequence selectivities were determined.

Questions

1–4 of 4 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

  4. Do you have references on the use of 2-Bromoacetophenone (also known as phenacyl bromide) Products 115835 and 77450 for making phenacyl esters of carboxylic acids for HPLC analysis?

    1 answer

    1. For information on the use of phenacyl bromide to derivatize carboxylic acids (e.g., fatty acids) for HPLC analysis, please see one or more of the following three references:1. K.J. Longmuir, et al., Determination of monoenoic fatty acid double bond position by permanganate-periodate oxidation followed by high-performance liquid chromatography of carboxylic acid phenacyl esters. Analytical Biochemistry, 167(2), 213-221 (1987). 2. T. Hanis et al.,  Determination of fatty acids as phenacyl esters in rat adipose tissue and blood vessel walls by high-performance liquid chromatography. Journal of Chromatography, 452, 443-457 (1988).3. A. Mehta et al., Rapid quantitation of free fatty acids in human plasma by high-performance liquid chromatography. Journal of Chromatography B Biomedical Science Applications, 719(1-2), 9-23 (1998).
