The compound has a molecular weight of 121.18 g/mol and contains a basic amino group that can participate in various chemical reactions including acylation and alkylation.

3,5-dimethylaniline is primarily used as an intermediate in the synthesis of dyes, pigments, and pharmaceutical compounds. It serves as a building block for manufacturing various aromatic compounds and specialty chemicals in the chemical industry. The compound is also utilized in research and development applications, particularly in organic synthesis where substituted anilines are required for creating more complex molecular structures.

3,5-dimethylaniline must be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Acute Tox. 3 classification. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. The compound requires careful handling as indicated by the GHS06 and GHS08 pictograms, signaling both acute toxicity and health hazards.

3,5-dimethylaniline should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Storage areas must be designed to prevent environmental release due to its Aquatic Chronic 2 classification. The container should be kept away from oxidizing agents and strong acids, and storage facilities should include appropriate containment measures for spill control and environmental protection.

Skin contact with 3,5-dimethylaniline requires immediate removal of contaminated clothing and thorough washing with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention, providing the safety data sheet to medical personnel.

3,5-dimethylaniline disposal must comply with local, national, and EU waste regulations as it is classified as hazardous waste. The compound cannot be disposed of via regular waste streams due to its toxicity and environmental impact classifications. Disposal should be conducted through licensed hazardous waste treatment facilities that can handle aromatic amines safely, ensuring proper neutralization and preventing environmental contamination.

3,5-dimethylaniline is classified under ADR Class 6.1 (toxic substances) Packing Group II, requiring specific packaging, labeling, and documentation for transport. Shipments must display appropriate hazard labels including GHS06, GHS08, and GHS09 pictograms with 'Danger' signal word. Transport must comply with dangerous goods regulations, using UN-approved packaging and following proper loading, segregation, and emergency response procedures during transit.

3,5-dimethylaniline is regulated under EU CLP Regulation with multiple hazard classifications including Acute Tox. 3 and STOT RE 2. The compound falls under REACH regulation requiring registration and compliance with supply chain communication requirements. While not currently listed as SVHC, its toxic properties subject it to various occupational safety regulations and environmental protection measures across EU member states.
