 (mĕth′ə-lə-mēn′, -lăm′ēn, mə-thĭl′ə-mēn′)
A toxic flammable gas, CH5N, produced by the decomposition of organic matter and synthesized for use as a solvent, in tanning, and in the manufacture of many products, such as dyes and insecticides.


(Elements & Compounds) a colourless flammable water-soluble gas, used in the manufacture of herbicides, dyes, and drugs. Formula: CH3NH2


(ˌmɛθ ə ləˈmin, -əlˈæm ɪn)

any of three derivatives of ammonia in which one or all of the hydrogen atoms are replaced by methyl groups, esp. a gas, CH5N, with an ammonialike odor.

Cobalt ferrite nanoparticles (Co[Fe.sub.2][O.sub.4]) were synthesized by hydrothermal coprecipitation of aqueous solutions of cobalt (II) nitrate and iron (III) chloride in alkaline medium (methylamine), according to a well-known procedure [45, 46].
But, this could not infuse much intension till when Vayssieres et al [123] successfully used the technique for the controlled synthesis of ZnO nanorods on glass and Si substrates by the thermal decomposition of methylamine and zinc nitrate.
We also observed in WT exposed females lower choline levels and its main metabolites, tri- methylamine and trimethylamine oxide, which are both derived from dietary choline fermentation by commensal bacteria than in WT females fed control chow (Craciun and Balskus 2012).
Also seized during the operation were large amounts of controlled precursors and essential chemicals (CPECs) used in the manufacture of shabu consisting of 1-phenyl -2 propanone, methylamine, acetic acid, sodium hydroxide, sodium acetate, potassium iodate, sodium sulfate, tartaric acid, boric acid, methanol, ethanol and ammonium hydroxide; and safrole, a chemical used in the production of ecstasy, a party drug.
Methylamine molecules are driven out of the device in response to solar heat, which darkens the window.
Following, the analyses were hydrolyzed in a post- column reaction with 0.075 N sodium hydroxide (NaOH) at 80[degrees]C to form methylamine which reacted with ophthalaldehyde (OPA) and 2- mercaptoethanol forming a compound identifiable in a fluorescence detector.

All the chemicals used for the device fabrication were purchased from Aldrich except methylamine (40% in methanol) which was purchased from Tokyo Chemical Industry Co.
Besides numerous metabolites, intestinal flora produces methylamine, including TMA, dimethylamine, and monomethylamine.
In another 1H-NMR human study, several metabolites (maltose, glucose, biotine, methylamine, inosine, methylguanidine, creatine, myoinositol, and quinolinic acid) were found significantly changed in septic neonates at the onset of the disease [28].
The change in color comes from molecules (methylamine), which are driven out of the window device when exposed to sunlight (below 3% visible transmittance), and reversibly absorbed into the device, returning the absorber layer made of a metal halide perovskite-methylamine complex to the transparent state (68% visible transmittance) as the device cools back down.
