Allgemeine Beschreibung

4,4′-Dipyridyl (BPY) is an organic linker mainly used in the preparation of coordination polymers. It is a pyridine derivative in which pyridyl groups can rotate along the carbon-carbon structure. It can be used as a catalyst for photoelectrochemical reduction.[1][2][3]
4,4′-bpy is popularly used to bridge metal centers to form coordination polymers with novel properties.[4] 4,4′-bpy ligands can mediate electronic effects between paramagnetic metals ions by stabilizing the magnetic ordering.[5]

Anwendung

4,4′-Dipyridyl (4,4′-bipyridine, 4,4′-bpy) and Co (NCS)2 solutions were interdifussed to form single crystals Co(NCS)2(4,4′-bipy)2·2(CH3CH2)2O and Co(NCS)2(4,4′-bipy)2·2(CH3CH2)2O.[6]
BPY is a ligand that forms a network between the transition metals which results in the formation of coordination bond.[7] Hybrid nanosheets can be prepared by using a coordination polymer and BPY as a complex linker.[1] It consists of two active sites which can be used for the development of drugs.[8]

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
