CH3NCH2CH2NH2

CH3NCH2CH2NH2, also known as N-methylethylenediamine, is an organic compound with the chemical formula C3H10N2. It is a diamine, meaning it contains two amine functional groups. One amine group is a secondary amine, with a methyl group attached to the nitrogen atom, and the other is a primary amine. The molecule consists of a three-carbon chain, with a nitrogen atom at each end, and a methyl group attached to one of the nitrogen atoms.

N-methylethylenediamine is a colorless liquid at room temperature and pressure. It is soluble in water and many organic solvents. Like other amines, it is basic in nature due to the lone pair of electrons on the nitrogen atoms. This basicity allows it to react with acids to form salts. It can also participate in reactions typical of primary and secondary amines, such as acylation and alkylation.

The compound finds use as a building block in the synthesis of various organic molecules. It can be incorporated into polymers, dyes, and pharmaceuticals. Its structure, featuring both a primary and a secondary amine, makes it a versatile reagent for creating more complex molecular architectures. It is also employed as a curing agent for epoxy resins and as a corrosion inhibitor. Safety precautions should be taken when handling N-methylethylenediamine due to its potentially irritating and corrosive properties.
