一般說明

我们致力于为您带来更加绿色的替代产品，这些产品遵守一项或多项绿色化学12项原则。乙醇是一种绿色环保溶剂，符合“更安全的溶剂和助剂”以及“使用可再生原料”的原则。 
纯乙醇是一种非变性的2000proof乙醇。乙醇，一种伯醇，是合成各种化合物的重要原料。它可以通过糖蜜的发酵或乙烯的水合作用而合成。在氢氧化钠存在下，它在羰基化合物的转移氢化过程中可起到氢源和反应介质的作用。[1]乙醇/水熏蒸对柴油发动机性能的影响已被研究。[2]无水级溶剂具有极低的水百分比和低残留水平。

應用

乙醇已用于：
  • 作为洛伐他汀的溶剂。[3]
  • 作为合成(S)-4-羟基-2-酮-4-(2'-吡啶基)丁酸酯中的一种溶剂。[4]
  • 在激光捕获显微切割（LCM）中将组织切片固定在玻片上。[5]

Questions

1–10 of 13 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. 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.

      Helpful?

  4. 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.

      Helpful?

  5. 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.

      Helpful?

  6. What is 190 proof and 200 proof ethanol?

    1 answer

    1. All non-denatured ethanol products have a proof associated with the product description. The proof is a measure of the water content of the ethanol portion of the product. The proof is calculated as two times (2 x) the actual ethanol concentration by volume.

      Helpful?

  7. Is Product 459836, Ethanol, DNase, RNase, and Protease free?

    1 answer

    1. This product is not tested for the presence of DNases, RNases, and proteases. However, Sigma-Aldrich does offer ethanol products that are tested for these impurities. Ethanol products that are part of the BioUltra product line, and for applications in molecular biology, are required to be DNase, RNase, protease, and phosphatase free.

      Helpful?

  8. 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.

      Helpful?

  9. 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.

      Helpful?

  10. What are the options for drying solvents?

    1 answer

    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 such as molecular sieves, which are typically compatible with organic solvents.
