N,N-Dimethylphenethylamine

Updated: 2026-07-29

Overview

N,N-Dimethylphenethylamine is a synthetic organic compound belonging to the substituted phenethylamine class. Structurally, it consists of a phenethylamine core with two methyl groups attached to the nitrogen atom, classifying it as a tertiary amine. First synthesized in the early 20th century, this compound has found niche applications in pharmaceutical research and specialty chemical synthesis. The compound's molecular structure gives it both lipophilic and basic properties, making it useful as a building block for more complex molecules. While not widely used in commercial products, it serves as an important intermediate in medicinal chemistry research, particularly in studies of neurotransmitter analogs and psychoactive substances.

Physical and Chemical Properties

As a liquid at room temperature, N,N-Dimethylphenethylamine displays typical amine characteristics including volatility and a fishy odor at higher concentrations. The compound's density of approximately 0.93 g/cm³ makes it slightly less dense than water. Its boiling point range of 210-215°C indicates moderate thermal stability, though it should be protected from prolonged heat exposure. Chemically, the compound acts as a weak base, forming salts with acids. The electron-donating methyl groups increase the nitrogen's basicity compared to primary amines. In solution, it can participate in various organic reactions including acylation, alkylation, and reductive amination. The phenyl ring makes it susceptible to electrophilic aromatic substitution under appropriate conditions.

Main Applications

The primary industrial use of N,N-Dimethylphenethylamine lies in pharmaceutical research, where it serves as a precursor for synthesizing more complex drug candidates. Medicinal chemists value its structural features for developing compounds that interact with neurological targets. The molecule's phenethylamine scaffold is particularly relevant for designing potential CNS-active compounds. In specialty chemical production, this amine finds use as a building block for dyes, surfactants, and corrosion inhibitors. Some fragrance manufacturers employ derivatives of this compound as synthetic intermediates. Research laboratories may use it as a reference standard in analytical chemistry or neuropharmacology studies.

Safety and Storage

Proper handling of N,N-Dimethylphenethylamine requires standard laboratory precautions including chemical-resistant gloves, eye protection, and adequate ventilation. The liquid can cause skin and eye irritation upon contact, and its vapors may irritate respiratory passages. Being flammable, it should be kept away from ignition sources and stored in approved safety cabinets. For long-term storage, amber glass bottles with PTFE-lined caps are recommended to prevent degradation. The chemical should be maintained under inert atmosphere when possible, especially for high-purity grades. Secondary containment is advised to contain potential spills. Shelf life typically ranges from 1-2 years when stored properly at temperatures below 25°C.

B2B Procurement Guide

Industrial buyers should prioritize suppliers who provide comprehensive Certificates of Analysis (CoA) detailing purity (typically 97-99%), water content, and impurity profiles. Pharmaceutical-grade material requires additional documentation including residual solvent analysis and heavy metal testing. Batch-to-batch consistency is particularly important for research applications. Consider ordering smaller test quantities before committing to bulk purchases to verify quality. Pricing varies significantly based on purity (technical grade vs. analytical standard) and order volume. For international shipments, confirm the compound's regulatory status in both origin and destination countries, as some jurisdictions control phenethylamine derivatives. Lead times may range from 2-6 weeks for specialty grades.
