  • Ethyl Methy
  • We report on the tentative detection of $trans$ Ethyl Methyl Ether (tEME), $t-CH_3CH_2OCH_3$, through the identification of a large number of rotational lines from each one of the spin states of the molecule towards Orion KL. (archives-ouvertes.fr)
  • solvent
  • TAME can be used as a safe reaction medium (e.g. condensation reactions, coupling reactions, such as Grignard reactions and Suzuki reactions, as well as metal hydride reductions) and as an extraction solvent to replace dichloromethane, aromatics, and other ethers. (wikipedia.org)
  • It is a relative fast-evaporating glycol ether acetate, and it sets a performance standard in high-solids, solvent-borne systems. (sbwire.com)
  • It is also used as a solvent in academic research, although it is less commonly used than diethyl ether. (wikipedia.org)
  • ketone
  • As a result, even slightly polar solvents of any variety, such as ethyl acetate or methyl ethyl ketone, are avoided when using this reagent as they competitively associate with the reagent. (wikipedia.org)

  • ISBN 0-471-16019-9 Synthesis of Alpha-Halo Ethers from Symmetric Acetals and In Situ Methoxymethylation of an Alcohol, Organic Syntheses, Vol. 84, No. 102 (2007) R.J. Linderman, M. Jaber, B.D. Griedel, J. Org. (wikipedia.org)
  • group
  • MTBE is extensively used in industry as a safer alternative to diethyl ether (which is commonly used in academic research) as the tert-butyl group prevents MTBE from forming potentially explosive peroxides. (wikipedia.org)
  • In the chemical sciences, methylation denotes the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group. (wikipedia.org)
  • Methylation is a form of alkylation, with a methyl group, rather than a larger carbon chain, replacing a hydrogen atom. (wikipedia.org)
  • The overall reaction transforms 5-methyltetrahydrofolate (N5-MeTHF) into tetrahydrofolate (THF) while transferring a methyl group to Hcy to form Met. (wikipedia.org)
  • The enzyme is initially primed into a reactive state by the transfer of a methyl group from N5-MeTHF to Co(I) in enzyme-bound cobalamin (Cob), forming methyl-cobalamin(Me-Cob) that now contains Me-Co(III) and activating the enzyme. (wikipedia.org)
  • The activated methyl group is transferred from Me-Cob to the Hcy thiolate, which regenerates Co(I) in Cob, and Met is released from the enzyme. (wikipedia.org)
  • groups
  • We also provide maps of $CH_3OCOH$, $CH_3CH_2OCOH$, $CH_3OCH_3$, $CH_3OH$, and $CH_3CH_2OH$ to compare the distribution of these organic saturated O-bearing species containing methyl and ethyl groups in this region. (archives-ouvertes.fr)
  • Arginine can be methylated once (monomethylated arginine) or twice, with either both methyl groups on one terminal nitrogen (asymmetric dimethylarginine) or one on both nitrogens (symmetric dimethylarginine), by protein arginine methyltransferases (PRMTs). (wikipedia.org)
