C6H5CH2NCH33

C6H5CH2NCH33 refers to the compound N,N-dimethylbenzylamine, a tertiary amine that features a benzyl substituent attached to a dimethylamino group. In common usage the molecule is written as N,N-dimethylbenzylamine or dimethylbenzylamine. Its molecular formula is C9H13N and its approximate molecular weight is 135.2 g/mol. Structurally, it consists of a phenyl ring attached to a CH2 group, which in turn is bonded to a nitrogen atom bearing two methyl groups.

Physical and chemical properties are typical of tertiary amines: it is generally a colorless liquid or oil with a mild, amine-like odor. It is more soluble in organic solvents than in water and can form salts with acids. As a base, it can act as a nucleophile and is susceptible to alkylation or acylation in appropriate reactions.

Synthesis methods include reductive amination of benzaldehyde with dimethylamine followed by reduction, or Eschweiler–Clark methylation of benzylamine using formaldehyde and formic acid to furnish the N,N-dimethyl derivative. An alternative laboratory route is the alkylation of benzylamine with methylating agents under suitable conditions to install the N,N-dimethyl functionality.

Applications of N,N-dimethylbenzylamine center on its use as an intermediate in organic synthesis. It serves as a building block for the preparation of more complex tertiary amines, and can participate in various transformations relevant to pharmaceuticals, dyes, and specialty chemicals. It can also form quaternary ammonium salts, which have utility in catalysis or as phase-transfer agents.

Safety considerations include handling as with other tertiary amines: avoid inhalation and skin contact, use in a well-ventilated area, and store away from oxidizers. It is mildly corrosive to eyes and skin and can be irritating.
