General description

Methylamine hydrochloride is used as a buildingblock for the synthesis of various organic compounds.

Application

Methylamine hydrochloride can be used as a reactant to synthesize:
  • Betahistine via aza-Michael reaction with 2-vinylpyridine in water.
  • Azatripyrrolic and azatetrapyrrolic macrocycles by reacting with pyrrole and formaldehyde via base-catalyzed Mannich reaction.
  • Tetrahydropyridines via Aza-Diels–Alder reaction with dienes and aldehydes.
  • N-methylsecondary arylamines from aryl chlorides via nickel-catalyzed amination reaction.

Single-walled carbon nanotubes (SWCNTs) have been functionalized with highly selective tetraphosphonate cavitand receptors. The binding of charged N-methylammonium species to the functionalized SWCNTs was analyzed by X-ray photoelectron spectroscopy and confirmed by (31)P MAS NMR spectroscopy. The cavitand-functionalized SWCNTs were

Luminex-based anti-HLA IgG detection on single-antigen flow beads (SAFB) represents a valuable tool for characterization of allosensitization patterns. Assay interpretation, however, may be impeded by false-low test results caused by the prozone effect. Recent experimental data have related this artifact

Ammoniomethyl trifluoroborates are very powerful reagents that can be used to access biologically relevant aryl- and heteroaryl-methylamine motifs via Suzuki-Miyaura cross-couplings. Until now, this method was limited to the production of tertiary and primary amines. The synthesis of a large

Ammonia is the preferred nitrogen source for many algae including the cyanobacterium Synechococcus elongatis (Synechococcus R-2; PCC 7942). Modelling ammonia uptake by cells is not straightforward because it exists in solution as NH(3) and NH (4) (+) . NH(3) is
