Methylamine hydrochlorideProduct Name:Methylammonium chlorideCAS Registry Number: 593-51-1Molecular Formula:CH5N.HClMolecular Weight:67.52EINECS:209-795-0Purity:99%Grade:Industrial GradeAppearance: white to light tan solidMelting Point: 230 CWater Solubility: moderateStability: Stable, but may be moisture sensitive. Incompatible with strong oxidizing agents.Uses: Methylamine hydrochloride is Used as basic raw materials, such as fuel, pesticides, oil pharmaceuticals, and other organic synthesis.Representative commercially significant chemicals produced from methylamine include the pharmaceuticals and theophylline, the pesticides carbofuran, carbaryl, and metham sodium, and the solvents N-methylformamide and N-methylpyrrolidone. The preparation of some surfactants and photographic developers require methylamine as a building block. Description:Methylamine is an organic compound with a formula of CH3NH2. This colorless gas is a derivative of ammonia, but with one H atom replaced by a methyl group. It is the simplest primary amine. It is sold as a solution in methanol, ethanol, THF, and 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 fish. Methylamine is used as a building block for the synthesis of many other commercially available compounds.In the laboratory methylamine hydrochloride is readily prepared by various other methods. One method entails treating formaldehyde with ammonium chloride.Methylamine is a good nucleophile as it is highly basic and unhindered, although, as an amine it is considered a weak base. Its use in organic chemistry is pervasive. Some reactions involving simple reagents include: with phosgene to methyl isocyanate, with carbon disulfide and sodium hydroxide to the sodium methyldithiocarbamate, with chloroform and base to methyl isocyanide and with ethylene oxide to methylethanolamines. Liquid methylamine has solvent properties analogous to those for liquid ammonia.Representative commercially significant chemicals produced from methylamine include the pharmaceuticals ephedrine and theophylline, the pesticides carbofuran, carbaryl, and metham sodium, and the solvents N-methylformamide and N-methylpyrrolidone. The preparation of some surfactants and photographic developers require methylamine as a building block.Methylamine arises as a result of putrefaction and is a substrate for methanogenesis.Additionally, methylamine is produced during PADI4-dependent arginine demethylation.
