General description

Methylamine (CH3NH2) is a simple aliphatic primary amine used as a chemical intermediate in organic synthesis. It is prominently used in the production of pesticides and solvents.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Methylamine can be used as a reagent in the synthesis of the following:     
  • Methylmorpholine from diethylene glycol.       
  • N-methylalkylamines from oxoamines via formation of imine, followed by hydrogenation using Ni catalyst.   
  • N-Methyldipropylenetriamine by reacting with acrylonitrile, followed by hydrogenation.  
  • N-methyl hydroxypyrrolidines from chlorohydrin in the presence of NaCNBH as a reducing agent.       
  • 2-(Methylamino)-6,7-dichloro-1,4-anthracenedione by reacting with 6,7-dichloro-1,4-anthracenedione.

Methylamine solution 2.0 M in THF can be used as a precursor that facilitates the synthesis of perovskite based materials. It can also be used as a deactivating agent to study the catalytic performance of acidic macroporous ion exchange resins. It can be annealed to reduce impurity in the grain boundaries, improve the stability and efficiency of the perovskite solar cells.

A convergent and stereoselective synthesis of 2,5-disubstituted 3-hydroxypyrrolidines has been developed that involves reductive annulation of β-iminochlorohydrins, which are readily available from β-ketochlorohydrins, and provides rapid access to a variety of 2,5-syn-pyrrolidines. Application of this process to the concise (three-step)

Despite the widespread use of solution-processable hybrid organic-inorganic perovskites in photovoltaic and light-emitting applications, determination of their intrinsic charge transport parameters has been elusive due to the variability of film preparation and history-dependent device performance. Here we show that screening
