Methylamine is sold as a solution in methanol, ethanol, tetrahydrofuran, or water, or as the anhydrous gas in pressurized metal containers. Industrially, methylamine is transported in its anhydrous form in pressurized railcars and tank trailers. It has a strong odor similar to rotten fish.

Hazard pictograms are one of the key elements for the labelling of containers under the GHS, along with: [2] an identification of the product; a signal word – either Danger or Warning – where necessary; hazard statements, indicating the nature and degree of the risks posed by the product
Methylamine is crucial to all such methods and is produced from the model airplane fuel nitromethane, or formaldehyde and ammonium chloride, or methyl iodide with hexamine. [99] This was once the preferred method of production by motorcycle gangs in California, [100] until DEA restrictions on the chemicals made the process difficult.
Ferrous picrate is used in some applications as a diesel fuel additive to achieve better mileage. [3]Sodium picrate is used as an etchant in metallography to differ preeutectoid ferrite in hypoeutectoid steel from preeutectoid cementite in hypereutectoid steel by etching cementite to a dark colour, whereas not attacking ferrite and thus it remains reflective.
In order to obtain high yields of the desired target product, the reactants are continuously fed to a flow reactor and reacted with a more than two-fold excess of methylamine. [3] In the downstream process steps, the excess methylamine and the water is removed and NMEA (bp. 160 °C) and MDEA (bp. 243 °C) are isolated from the product mixture ...
A 2004 BBC Radio 5 broadcast reported the site is contaminated with toxic chemicals including hexachlorocyclohexane and mercury, held in open containers or loose on the ground. [110] A drinking water sample from a well near the site had levels of contamination 500 times higher than the maximum limits recommended by the World Health Organization ...
It is an ammonium salt composed of methylamine and hydrogen chloride. One potential application for the methylammonium halides is in the production of perovskite solar cells . [ 3 ] [ 4 ] The methyl group and other hydrogen atoms are bonded covalently to the nitrogen, with the chloride bonded ionically .
