General description

Sodium hypochlorite (NaOCl) is a commonly used reagent in organic synthesis for many oxidation and chlorination reactions.[1]

Application

Sodium hypochlorite solution can be used as an oxidizing agent for the oxidation of:      
  • Primary alcohols to aldehydes or carboxylic acids and secondary alcohols to ketones.     
  • Aryl aldehydes to the corresponding acids in the presence of a phase-transfer catalyst.      
  • Ethers to esters by careful pH control (pH range of 8–9.5),

It can also be used as a reagent in the:      
  • Epoxidation of enones and polycyclic arenes.      
  • Oxidative degradation reaction      
  • N-Chlorination of primary and secondary amines
  • Enantioselective epoxidation of α, β-unsaturated ketones      
  • Asymmetric dihydroxylation of olefins in the presence of an osmium catalyst      
  • Chlorination of allylic carbons in the presence of CeCl3

Features and Benefits

  • Readily available reagent      
  • Easily handled oxidizing agent      
  • No phase-transfer catalyst is necessary for the oxidation of substrates in the pH range 10–11     
  • Simplified waste disposal and lower toxicity

Questions

1–4 of 4 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
