一般說明

Tetrachloro-1,4-benzoquinone (TCBQ) is a quinone compound with four chloride groups. The catalytic activity of quinone groups (benzoquinone) can be controlled by the chloride groups with large electronegativity.[1]

應用

可与二苯乙烯衍生物、α,β-不饱和羰基化合物发生光诱导的环加成反应。[2]荧光猝灭剂。[3]
用于通过氧化环化反应合成二苯并呋喃。[4]
TCBQ can form a nanocomposite with multi-walled carbon nanotubes (MWCNTs) on a graphite electrode for nicotinamide adenine dinucleotide (NADH) oxidation.[5] It can also provide pseudocapacitance and can be used as an electrode material for the development of supercapacitors.[6] It may be used as an organic cathode and act as a redox mediator for the fabrication of lithium ion batteries.[6][7]

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.
      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

  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
