N-ethyl-3-methylaniline

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

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

N-ethyl-3-methylaniline serves primarily as an intermediate in organic synthesis and chemical manufacturing. It is commonly used in the production of dyes, pigments, and pharmaceutical intermediates. The compound also finds applications in the synthesis of specialty chemicals, rubber processing aids, and as a building block for various nitrogen-containing organic compounds in fine chemical manufacturing and research applications.

Safe handling of N-ethyl-3-methylaniline requires appropriate personal protective equipment including chemical-resistant gloves, safety glasses, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid direct skin contact and ensure proper ventilation. Handle containers carefully to prevent spills, and maintain good hygiene practices including thorough handwashing after handling.

N-ethyl-3-methylaniline should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers in secondary containment to prevent environmental contamination in case of leaks. Store away from strong oxidizing agents and acids that could cause incompatible reactions. Ensure storage areas comply with local chemical storage regulations and maintain appropriate temperature control.

In case of skin contact with N-ethyl-3-methylaniline, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention.

N-ethyl-3-methylaniline waste must be disposed of through licensed hazardous waste disposal facilities in accordance with local and EU waste regulations. Do not discharge to sewers, waterways, or soil. Small quantities should be collected in appropriate containers and labeled clearly for hazardous waste collection. Consult local environmental authorities for specific disposal requirements and approved waste treatment facilities in your region.

N-ethyl-3-methylaniline is classified under ADR as Class 6.1 (Toxic substances), Packing Group II, indicating moderate toxicity requiring special transport precautions. Transportation must comply with ADR regulations including proper packaging, labeling, and documentation. Use appropriate packaging materials resistant to the chemical, ensure proper vehicle placarding, and follow routing restrictions. Only authorized carriers familiar with dangerous goods transport should handle shipments.

N-ethyl-3-methylaniline is subject to standard EU chemical regulations including REACH registration requirements for manufacturers and importers. It must comply with CLP regulation for classification and labeling, though currently it shows no specific GHS classification. The substance is not listed as a SVHC (Substance of Very High Concern). Users must follow general industrial chemical handling regulations and workplace safety requirements applicable in their jurisdiction.
