一般描述

硫代乙酰胺(TAA)是一种常用作腐蚀抑制剂的硫代羰基化合物。它通过在金属表面形成保护层来防止腐蚀。[1] 它能与D2O进行氘交换反应,得到N-二共酯硫代乙酰胺。硫代乙酰胺及其氘代衍生物(N-二共酯硫代乙酰胺)的红外光谱研究已有报道。[2]

应用

它也可以用作硫化物源来制备金属离子(如镉[3]、镍[4]、锌[5] 和铜)的金属硫化物。[6]
硫代乙酰胺已被用作合成CdS纳米颗粒所需的硫源[7]和量子点。[8]
肝毒素和致癌物质。[9]在利用固定化面包′酵母进行对映体选择性还原β-酮酯过程中,作为添加剂。[10]

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
