Allgemeine Beschreibung

Nonafluorobutane-1-sulfonic acid is a colorless liquid that can be considered as a superacid, which can be synthesized by reacting 1-iodononafluorobutane with sodium dithionite in the presence of sodium bicarbonate in acetonitrile/water. [1]

Anwendung

Nonafluorobutane-1-sulfonic acid may be used as catalyst in the synthesis of 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin[2] and N-benzylpyridin-2-amine[3].

Perfluorobutanesulfonic acid (PFBS) is used as the replacement of perfluorooctanesulfonic acid (PFOS) since 2000 because of the concern on PFOS' persistence in the environment and the bioaccumulation in animals. Accumulating evidence has shown the correlation between the exposure to perfluorinated

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. 1. 이 제품은 액체로 되어있습니다. 표준원액을 만들어야 하는데 피펫으로 끌어올렸을때 하얗게 굳습니다. 굳기전에 재빠르게 무게를 재서 표준원액을 조제하면 농도가 잘 맞지 않습니다. 어떻게 조제하는 것이 정확할까요? 2. 뚜껑을 열었을 때 연기가 나오는데 어떤 현상이 있는건가요 조심해야하나요? 2. 메탄올에 녹이는 것이 좋을까요?

    1 answer

    1. This product is a liquid at room temperature and will only become a solid at -21°C or colder. It is strongly recommended to review the Safety Data Sheet prior to working with this chemical. It is important to handle this chemical under an inert gas atmosphere, as it reacts violently with water and moisture in the air, likely causing the issues described. Additionally, it should be stored under inert gas.
