Description générale

Tetrabutylammonium hydroxide is a quaternary ammonium salt mainly used as a strong base and phase-transfer catalyst.[1] It can be synthesized from tetrabutylammonium iodide.[2]
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is highly effcient and enhance catalytic efficiency. Click here for more information.

Application

Tetrabutylammonium hydroxide solution (TBAOH) may be used in the following studies:
  • For the dissolution of 10wt% cellulose under room temperature conditions.[3]
  • As a catalyst during the synthesis of 1,2,4-oxadiazoles.[4]
  • Preparation of TBAOH salts of fatty acids.[5]

Attention

May crystallize below 30°C
Gentle warming and swirling should redissolve the solid

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.

  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
