Description générale

Dimethyl 2-oxoglutarate is a key intermediate formed during the Krebs cycle and an important nitrogen transporter in the biological metabolic pathways.[1] The electrochemical behavior of dimethyl-2-oxoglutarate has been investigated by cyclic voltammetry, square wave voltammetry and differential pulse voltammetry using a glassy carbon electrode.[1]

Application

Dimethyl 2-oxoglutarate can undergo cylocondensation with dinucleophiles, such as 1,2-phenylenediamine, 2-aminophenol and 2-aminobenzenethiol to form novel heterocycles.[2]
Dimethyl 2-oxoglutarate may be used to synthesize the conformationally constrained PNA (peptide nucleic acid) -monomer capable of binding thymine in a triplex motif.[3] It may be used in the synthesis of 4-aryl kainic acid analogs, via highly stereoselective Michael addition reaction with nitrostyrene.[4]

Increased glutamine metabolism is a hallmark of cancer. Mitochondrial glutamic pyruvate transaminase (GPT2) catalyzes the reversible transamination between alanine and α-ketoglutarate (α-KG), also known as 2-oxoglutarate, to generate pyruvate and glutamate during cellular glutamine catabolism. However, the precise role of

Questions

1–9 sur 9 questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 réponse

    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 réponse

    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. What is the recommended solvent for diluting product #349631-5g? Should it be diluted in DMSO, water, or a buffer such as PBS?

    1 réponse

    1. The recommended solvents for this chemical are DMSO at a concentration of 30 mg/ml, ethanol at 30 mg/ml, and PBS (pH 7.2) at 10 mg/ml.

  4. Hello, What is the concentration of this product in its liquid form? I see the molecular weight, but not the total concentration. How many grams were dissolved in the amount of solvent present?

    1 réponse

    1. This product is supplied as a neat or pure liquid with a density of 1.203 g/mL and a molecular weight of 174.15 g/mol. The minimum purity is 96%, thus the molarity will vary slightly from lot to lot. The molarity can range from 6.63M (96%) to 6.9M (100%). The lot specific purity is reported on the Certificate of Analysis.

      Molarity = density/MW * 1000 * concentration of the specific lot.

  5. Dear support, what is the shelf life of this product?

    1 réponse

    1. This product is not assigned an expiration date or recommended retest date. Products with no expiration date or recommended retest date should be routinely inspected by customers to ensure they perform as expected. These products are also subject to a one year warranty from the date of shipment.
