Allgemeine Beschreibung

4-Aminobenzoic acid (4-ABA) acts as an bacterial cofactor and participates in the synthesis of folic acid.[1] It is a versatile reagent for structure extension through linear hydrogen-bonding associations, involving both the carboxylic acid and amine functional groups.[1] Formation of 4-ABA monolayer film on glassy carbon electrode (GCE) by amino cation radical method has been described.[2] Molecular adducts of 4-ABA have been prepared and their characterization by infrared spectroscopy and X-ray diffration methods have been reported.[3]

Anwendung

4-Aminobenzoic acid may be used in the following studies:
  • Covalent modification of glassy carbon electrode.[4]
  • Synthesis of 1,4-(2-chlorobenzylidene)aminobenzoic acid (Schiff base).[5]
  • Spectrophotometric determination of the trace amounts of dopamine, methyldopa and levodopa.[6]
  • Synthesis of 1:1 proton-transfer compound with 5-sulfosalicylic acid.[1]

Questions

1–3 of 3 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

  3. Hallo, wie lange ist die Haltbarkeit des Produkts? auf dem Gebinde und dem Zertifikat gibt es dazu keine Angaben.

    1 answer

    1. This product is not assigned an expiration date or recommended retest date. Customers should routinely inspect products with no expiration date or recommended retest date to ensure they perform as expected. These products are also subject to a one-year warranty from the date of shipment.

      For more information, you may access the "Product Dating Information" document under "ADDITIONAL USEFUL DOCUMENTS ABOUT OUR PRODUCTS" at the bottom of the Quality Services page with this link: https://www.sigmaaldrich.com/life-science/quality-and-regulatory-management/quality-services.
