| Biological activity | N-methylbenzylamine is a phenylmethylamine compound. N-methylbenzylamine are found in carrots and N-methylbenzylamine can be used as potential biomarkers. |
| uses | pharmaceutical intermediates, organic solvents, also used in dye production and other organic synthesis. Used as an intermediate in medicine and dyes |
| Production method | It is obtained by the reaction of benzyl chloride and monomethylamine in benzene solvent. Add monomethylamine and benzene to the reaction pot, add benzyl chloride dropwise at 25 ℃, add it for about 5-6h, and heat up to 45 ℃ for 4h. Add sodium hydroxide and keep warm for another 1h. After standing and stratifying, the benzene layer is distilled to 140 ℃ under normal pressure, and then distilled under reduced pressure to collect 75-130 ℃(2.0-6.67kPa), and the fraction is benzyl methylamine. |
