N-phenylaniline

N-phenylaniline is an organic chemical compound with the molecular formula C12H11N and CAS number 122-39-4. It belongs to the class of aromatic amines and has a molecular weight of 169.22 g/mol. This substance is classified as hazardous with acute toxicity properties and potential for causing specific target organ toxicity after repeated exposure. It also poses environmental hazards to aquatic life.

N-phenylaniline is typically a solid crystalline substance at room temperature with a characteristic aromatic odor. It appears as white to pale yellow crystals or powder that may darken upon exposure to light and air. The compound has limited solubility in water but dissolves readily in organic solvents such as ethanol, benzene, and ether. It has a melting point around 53-54°C and demonstrates stability under normal storage conditions.

N-phenylaniline serves primarily as an intermediate in the synthesis of dyes, pharmaceuticals, and rubber chemicals. It is used in the production of antioxidants for rubber and plastics, as well as in the manufacture of various organic compounds. The substance also finds application in research and development activities within chemical laboratories and serves as a building block for more complex aromatic compounds in industrial chemical processes.

N-phenylaniline requires careful handling due to its acute toxicity classification. Personal protective equipment must include chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation. Given its GHS06 and GHS08 pictograms indicating toxicity and health hazards, minimize exposure and ensure proper training before handling this substance.

N-phenylaniline should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed to prevent contamination and oxidation. Store separately from incompatible materials such as strong oxidizing agents and acids. The storage area should be equipped with appropriate spill containment measures and clearly labeled with hazard warnings. Maintain inventory rotation to ensure product quality.

Immediate medical attention may be required for any exposure to N-phenylaniline due to its acute toxicity. In case of skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. For eye contact, flush immediately with plenty of water for at least 15 minutes. If inhaled, move to fresh air immediately. If ingested, do not induce vomiting and seek medical attention promptly.

N-phenylaniline disposal must comply with local and national hazardous waste regulations due to its toxic and environmentally hazardous properties. The substance cannot be disposed of in regular waste streams or sewerage systems. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small laboratory quantities may require special collection procedures. Maintain disposal records as required by environmental authorities.

N-phenylaniline is classified under ADR as Class 6.1 (toxic substances), Packing Group III, indicating moderate toxicity during transport. Packages must be properly labeled with appropriate hazard labels and documentation. Transport vehicles require placarding and drivers need ADR training certification. The substance must be packaged in UN-approved containers and segregated from incompatible materials during transport according to dangerous goods regulations.

N-phenylaniline is regulated under the CLP Regulation with its hazard classification and labeling requirements including the 'Danger' signal word and specific pictograms (GHS06, GHS08, GHS09). It falls under REACH registration requirements for chemical substances. The compound is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational health and safety regulations and environmental protection requirements.
