The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re-evaluated methylamine [74-89-574-89-5]. The critical effect is irritation of the nasal airways as observed in a 2-week study in rats with a NOAEC of 75 ml/m3.

Methylamine is the simplest aliphatic amine found in human urine. In the body it is thought to play a significant part in central nervous system disturbances observed during renal and hepatic disease and also has a role in general toxicity caused by oxidative stress.

Dihydrobis(methylamine)borate triiodide
Acta Crystallographica Section C Crystal Structure Communications, 2006Both cation and anion in the title compound, C2H12BN2+.I3-, lie on a crystallographic mirror plane and are bound in the lattice by N-H...I- hydrogen bonds, forming layers. Methyl-H-borane-H dihydride [-C-H(delta+)...(delta-)H-B-] interactions between molecules crosslink adjacent layers, giving ;sandwich' stacking along the a axis.

Enzymology of Methylamine Dehydrogenase
1996Methylamine dehydrogenase (MADH) belongs to the class of quinoprotein enzymes because it has tryptophyl tryptophanquinone (TTQ) as cofactor. In most cases, it is clear that the small blue copper protein, amicyanin, functions as natural electron acceptor.

Microwave Spectrum of Methylamine (I)
Journal of the Physical Society of Japan, 1953Microwave spectrum of methylamine molecule has been studied in the frequency range between 7 and 30 kMc/sec. More than two hundred lines and their Stark effects have been measured. These lines are divided into three kinds: (1) Δ J =0, Δ K =±1, (2) Δ J =±1, \(\varDelta K{=}{\mp}1\), and (3) Δ J =0, Δ K =0.

AbstractThe hydrogen‐transfer reaction catalysed by methylamine dehydrogenase (MADH) with methylamine (MA) as substrate is a good model system for studies of proton tunnelling in enzyme reactions—an area of great current interest—for which atomistic simulations will be vital.

The structure of liquid methylamine and solutions of lithium in methylamine
Molecular Physics, 2001The technique of hydrogen/deuterium isotopic substitution in neutron diffraction has been used to measure the intra- and intermolecular correlations in liquid methylamine, and 2 and 8 MPM (mole percent metal) lithium methylamine solutions. We find that pure methylamine forms only one strong hydrogen bond per molecule, with evidence for weaker ...

3,6-Dinitro-1,8-naphthyridine and its 2-substituted derivatives are dehydro-methylaminated with the solution of potassium permanganate in liquid methylamine (LMAPP) to the corresponding mono- or mono- and bis(methylamino)-3,6-dinitro-1,8-naphthyridines. In the case of 2-chloro- and 2-methoxy-3,6-dinitro-1,8-naphthyridine the replacement of chloro and
