Description générale

Pure ethyl alcohol is a non-denatured 200proof ethanol. Ethanol, a primary alcohol, is an important raw material for the synthesis of various compounds. It can be synthesized either from molasses by fermentation or by hydration of ethylene. It acts as a hydrogen source and reaction medium during the transfer hydrogenation of carbonyl compounds in the presence of sodium hydroxide.[1] The impact of ethanol/water fumigation on the performance of diesel engines has been studied.[2] Anhydrous grade solvents show extremely low percentage water and low residue levels.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Ethanol is environmentally preferable green solvent and thus it aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks". 

Application

Ethanol has been used:
  • as a solvent for lovastatin.[3]
  • as a solvent during the synthesis of (S)-4-hydroxy-2-keto-4-(2′-pyridyl)butyrate.[4]
  • to fix tissue sections on a slide during laser capture microdissection (LCM).[5]

Questions

1–10 of 13 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. How do I find the lot number for these reagents? I just recently purchased a 500mL bottle of this. Is the lot umber the same as the "source"?

    1 answer

    1. The lot number may be referred to on the label as the batch or source. The terminology may vary by brand and product type.

    1. Sigma-Aldrich offers a full range of high-purity solvents with extremely low water levels specifically manufactured for moisture sensitive organic and biotech applications.  Sigma-Aldrich also carries various drying agents, which are compatible with organic solvents. For drying ethanol, 3Å molecular sieves are a useful medium for removing any remaining water. For example, we offer these drying agents under such product numbers as 208574 and 208582.

  6. Can you recommend a Solvent Extractor for organics from aqueous solution?

    1 answer

    1. Solvent extractors are often used for the quantitative extraction of organics from aqueous solutions and separations in immunoassays. The MIXXOR system has been applied successfully in many laboratory solvent extraction operations and is ideal for the rapid screening of alternative solvents for specific extraction problems.

  7. How can I get help with the ATF paperwork for 190 and 200 proof ethanol?

    1 answer

    1. Because these non-denatured ethanol products are federally regulated, an ATF permit is required to purchase 190 and 200 proof ethanol. Sigma-Aldrich takes the hassle out of this process for you! There is no ATF paperwork needed or records to be kept on your part. Sigma-Aldrich holds the permit, and immediately pays the federal excise tax. For more regulatory information regarding the tax on ethanol, visit the U.S. Department of Justice, Bureau of Alcohol, Tobacco, Firearms and Explosives.

  8. Does Product 459836, Ethanol, contain any denaturants?

    1 answer

    1. This product does not contain any denaturants. A denaturant is an impurity (e.g. isopropyl alcohol, methyl alcohol, etc.) that is added to ethanol to make it unsuitable for consumption. Even though this ethanol is not denatured, it is still only suitable for research and development use and is not appropriate for human use products.

  9. What is the Department of Transportation shipping information for this product?

    1 answer

    1. Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
