General description

Ruthenium(III) chloride is a chemical compound, that can be used as a mild Lewis acid catalyst for the acetalization of aldehydes, acetalization of alcohols, and conversion of ketoximes to amides. [1] Additionally, it can also be used as a precursor to synthesize Ru nanoparticles.[2]

Application

Ruthenium(III) chloride is used as a catalyst:

  • In the synthesis of β‐amino alcohols by nucleophilic opening of epoxides with anilines.[2]
  • In the acetylation of varies of phenols, alcohols, thiols, and amines under mild conditions.[3]
  • In the synthesis of α‐aminonitriles by mixing aldehydes, amines, and trimethylsilyl cyanides.[4]

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.
      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. I have purchasedRuthenium(III) chloride, Ru content 45-55% from you company. However, I am confused on the statement of "Ru content 45-55%". If Ru is only hald of the materials, what are the other half? What is the purity of the chemical?

    1 answer

    1. The theoretical content of Ru in Ruthenium(III) chloride (RuCl3) should be 101.07 / 207.43 = ~48.72%, which falls into the specification range of this product. The other half of this product is mainly Cl ions. The Ru content is tested on a lot-to-lot basis. The purity can be roughly calculated using Ru content divided by 48.72%.

  4. What is the purity of this chemical?

    1 answer

    1. The Ruthenium content for this product ranges from 45-55 %. This value is determined by gravimetric analysis and ICP. The exact amount is lot-specific and is reported on the Certificate of Analysis of the batch received. The overall purity can be calculated by using the molecular weight of the Ruthenium(III) chloride.
