Description générale

Dibutyltin dilaurate, also known as dibutyltin didodecanoate, is a dibutyltin laurate hydroxide intermediate that is commonly used as a catalyst. It is also used in the transesterification reaction. [1]

Application

Dibutyltin dilaurate is used as a catalyst in:
  • The synthesis of polyurethane (PU) and polyhydroxyurethane (PHU) prepolymers and lignin urethane. [2] [3]
  • A protocol for the covalent attachment of poly(ethylene glycol) (PEG) to silicon oxide to form a hydrophilic non-fouling surface.[4]
  • Preparation of polymers by reacting hydroxyl-terminated macromonomers and aliphatic diisocyanates.[5][6][7][8]

Questions

1–3 of 3 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

  3. What is the concentration of item 291234?

    1 answer

    1. The concentration (Molarity) of item 291234 can be calculated using the formula: Density x Volume x Concentration / Molecular weight = Molarity. For example, if the density is 1.066g, the volume is 1000, and the molecular weight is 631.59, the resulting molarity would be 1.69M.
