N,N-diethyl-4-nitrosoaniline

N,N-diethyl-4-nitrosoaniline is an organic chemical compound with the molecular formula C10H14N2O and CAS number 120-22-9. This aromatic amine derivative features a nitroso group (-NO) attached to the benzene ring and two ethyl groups bonded to the nitrogen atom. With a molecular weight of 178.23 g/mol, it belongs to the class of nitrosoanilines and exhibits characteristic properties of aromatic nitroso compounds.

N,N-diethyl-4-nitrosoaniline typically appears as a crystalline solid at room temperature with a characteristic color ranging from yellow to orange-red due to the nitroso chromophore. The compound exhibits moderate solubility in organic solvents such as ethanol and acetone, while showing limited water solubility. Its aromatic structure contributes to its stability under normal conditions, though nitroso compounds can be sensitive to light and heat.

N,N-diethyl-4-nitrosoaniline serves primarily as an intermediate in organic synthesis and chemical manufacturing processes. It is commonly utilized in the production of dyes, pigments, and pharmaceutical intermediates. The compound also finds applications in analytical chemistry as a reagent for detecting certain metal ions and in research laboratories for synthesizing more complex organic molecules containing the nitrosoaniline structure.

Safe handling of N,N-diethyl-4-nitrosoaniline requires standard laboratory safety practices including wearing appropriate personal protective equipment such as safety glasses, gloves, and lab coats. Work should be conducted in well-ventilated areas or under fume hoods to minimize inhalation exposure. Avoid direct skin and eye contact, and prevent ingestion. Use proper tools for transferring the material and ensure all personnel are trained in chemical handling procedures.

N,N-diethyl-4-nitrosoaniline should be stored in a cool, dry place away from direct sunlight and heat sources to prevent degradation. Keep containers tightly sealed in their original packaging to maintain product integrity. Store separately from strong oxidizing agents and incompatible materials. Ensure storage areas have adequate ventilation and temperature control, preferably below room temperature to enhance stability and shelf life.

In case of skin contact with N,N-diethyl-4-nitrosoaniline, immediately wash the affected area with plenty of soap and water for at least 15 minutes. For eye contact, flush thoroughly with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult safety data sheets for specific first aid measures.

N,N-diethyl-4-nitrosoaniline must be disposed of according to local and national waste regulations as a chemical waste. Contact licensed waste disposal companies specialized in handling organic chemicals. Never dispose of the substance down drains or in regular trash. Small laboratory quantities may require specific collection procedures, while larger amounts need professional hazardous waste management. Always check local environmental regulations before disposal.

N,N-diethyl-4-nitrosoaniline is classified under ADR Class 4.2 (substances liable to spontaneous combustion) with Packing Group II. Transportation must comply with dangerous goods regulations, requiring appropriate packaging, labeling, and documentation. Packages must be properly marked with the correct shipping name and hazard labels. Transport vehicles need adequate ventilation and drivers require dangerous goods training certification for this classification.

N,N-diethyl-4-nitrosoaniline falls under general chemical regulations including REACH registration requirements for manufacture and import in the European Union. The substance is not classified as an SVHC (Substance of Very High Concern) under current regulations. However, standard occupational health and safety regulations apply for workplace handling. Always consult current regulatory databases and safety data sheets for the most up-to-date compliance requirements.
