General description

Sodium ethoxide (Sodium ethylate) is a sodium alkoxide. It has been synthesized by reacting sodium with ethanol. It undergoes decomposition in the presence of water to afford ethanol and sodium hydroxide. It is widely employed as a strong base in organic synthesis studies.[1]

Application


  • Organic solvent fractionation in lignin depolymerization: A study focused on enhancing the monophenolic yield of lignin depolymerization using a dualistic aprotic solvent system, employing sodium ethoxide for effective organic solvent fractionation. This approach underscores the versatility of sodium ethoxide in complex organic synthesis and biomass processing (Xu et al., 2024).

  • Solid-state self-quenching-resistant sulfur dots: Research on sulfur dots utilized a solvent-type passivation strategy to control solid-state self-quenching-resistant behavior, where sodium ethoxide played a crucial role in the synthesis process. This study illustrates sodium ethoxides utility in advanced materials synthesis, particularly for optoelectronic applications (Wu et al., 2022).

  • Synthesis of corrosion inhibitors: Sodium ethoxide was used in the efficient synthesis of 6,7-Dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile compounds, demonstrating its applicability as a base in the synthesis of corrosion inhibitors for steel alloys. This application combines computational and practical approaches to highlight sodium ethoxide′s role in materials science and corrosion prevention (Abd El-Lateef et al., 2022).

  • Colon-targeted drug delivery systems: The design and synthesis of Thieno[2,3-b]pyridines-chitosan nanocomposites for colon targeting employed sodium ethoxide. This research showcases sodium ethoxides application in the preparation of targeted drug delivery systems, focusing on enhancing the efficacy and specificity of pharmaceutical treatments (Mansour et al., 2020).

  • Synthesis of antimicrobial compounds: Sodium ethoxide was integral in the synthesis of novel bis-alpha,beta-unsaturated ketones and nicotinonitrile derivatives, aimed at antimicrobial applications. This study highlights the compound′s critical role in the development of new antimicrobial agents, demonstrating its utility in medicinal chemistry (Altalbawy, 2013).

Questions

1–4 of 4 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
