Description générale

N,N,N′,N′-Tetramethylethylenediamine (TMEDA) is a bidentate tertiary amine. It is a Lewis base having good solvating properties. It is useful ligand for organolithium chemistry.[1] Ultrafast molecular structural dynamics of the charge transfer in N,N,N′,N′-tetramethylethylenediamine has been studied by Rydberg fingerprint spectroscopy.[2]

Application


  • Hydrogenolysis of Cationic Half-Sandwich Zinc Complexes Containing a Chelating Amine: Facile Cleavage of Zinc-Carbon Bond by Dihydrogen To Give Zinc Hydride Cations.: This research explores the hydrogenolysis of cationic zinc complexes facilitated by N,N,N′,N′-Tetramethylethylenediamine (TMEDA), emphasizing the cleavage of zinc-carbon bonds, contributing significantly to catalyst development and organic synthesis (Mahawar et al., 2024, DOI: 10.1002/chem.202401262).

  • Electrophoresis.: This study highlights the use of TMEDA in electrophoresis applications, enhancing the resolution and efficiency of protein and nucleic acid separations, vital for biochemical research (Sonagra & Dholariya, 2024, PubMed ID: 36251838).

  • Dihydrogen Cleavage by a Zinc-Zinc Bond of a Heteroleptic Dizinc(I) Cation.: TMEDA is utilized in the activation of zinc-zinc bonds for hydrogen cleavage, demonstrating its importance in inorganic chemistry and catalyst development (Mahawar et al., 2024, DOI: 10.1021/acs.inorgchem.4c01116).

  • Nontoxic Initiator Alternatives to TEMED for Redox Hydrogel Polymerization.: The study investigates safer alternatives to TMEDA for hydrogel polymerization, essential for biomedical applications and polymer chemistry (Pumford et al., 2024, DOI: 10.1021/acsabm.3c01264).

  • Photoinduced Alkylsulfonylation and Cyanoalkylsulfonylation of Morita-Baylis-Hillman Adducts via Multicomponent Insertion of Sulfur Dioxide.: This paper discusses the role of TMEDA in facilitating multicomponent reactions for organic synthesis, crucial for developing new synthetic methodologies (Song et al., 2024, DOI: 10.1021/acs.joc.4c00052).

Questions

1–2 of 2 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.
