N-ethyl-3-methylaniline

N-ethyl-3-methylaniline is an aromatic amine compound with the molecular formula C9H13N and CAS number 102-27-2. This organic chemical belongs to the aniline family, characterized by an ethyl group attached to the nitrogen atom and a methyl group at the meta position of the benzene ring. With a molecular weight of 135.21 g/mol, it serves as an important intermediate in chemical synthesis and industrial applications.

N-ethyl-3-methylaniline is typically a liquid at room temperature with a characteristic amine odor. As an aromatic amine with molecular formula C9H13N, it exhibits moderate polarity due to the nitrogen atom while maintaining lipophilic characteristics from the aromatic ring and alkyl substituents. The compound shows limited water solubility but good solubility in organic solvents such as alcohols, ethers, and aromatic hydrocarbons.

N-ethyl-3-methylaniline serves primarily as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. It is commonly used in the production of dyes, pigments, and colorants for various industrial applications. The compound also finds application in the synthesis of specialty chemicals, agrochemicals, and as a building block for more complex organic molecules in research and development laboratories.

N-ethyl-3-methylaniline should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation exposure. Prevent skin and eye contact, as aromatic amines can be absorbed through the skin. Use non-sparking tools and ensure proper grounding to prevent static electricity buildup during handling operations.

N-ethyl-3-methylaniline should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep away from strong oxidizing agents, acids, and incompatible materials. Store in original containers with proper labeling and maintain temperatures below 25°C when possible. Ensure storage areas have appropriate spill containment measures and emergency equipment readily available.

Skin contact with N-ethyl-3-methylaniline requires immediate removal of contaminated clothing and thorough washing with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek medical attention. Always consult a physician if symptoms develop.

N-ethyl-3-methylaniline disposal must comply with local and national hazardous waste regulations. The substance should be collected in appropriate containers and disposed of through licensed hazardous waste disposal facilities. Never discharge into sewers, waterways, or soil. Small laboratory quantities may be suitable for incineration at authorized facilities with appropriate emission controls. Always consult local environmental authorities for specific disposal requirements.

N-ethyl-3-methylaniline is classified under ADR as Class 6.1 (Toxic substances) Packing Group II, requiring specific transport protocols for dangerous goods. Packages must be properly labeled with appropriate hazard markings and transported by qualified carriers with ADR certification. Use approved packaging that meets UN specifications and ensure proper documentation including transport emergency cards accompanies shipments.

N-ethyl-3-methylaniline is subject to REACH regulation requiring registration for manufacture or import above one tonne per year in the EU. The substance must comply with CLP regulation for classification and labeling requirements. While not currently listed as a Substance of Very High Concern (SVHC), users must follow standard chemical safety protocols and maintain safety data sheets for workplace compliance.
