2-nitroaniline

2-nitroaniline is an aromatic amine compound with the chemical formula C6H6N2O2 and CAS number 88-74-4. This organic chemical features both an amino group (-NH2) and a nitro group (-NO2) attached to a benzene ring in ortho position. With a molecular weight of 138.12 g/mol, it appears as a yellow to orange crystalline solid and is classified as a hazardous substance requiring careful handling due to its acute toxicity properties.

2-nitroaniline is a yellow to orange crystalline solid at room temperature with a molecular weight of 138.12 g/mol. It has a melting point around 71-73°C and exhibits limited solubility in water but dissolves well in organic solvents like ethanol and acetone. The compound has a characteristic aromatic odor and is stable under normal conditions, though it should be protected from strong oxidizing agents and excessive heat.

2-nitroaniline is primarily used as an intermediate in the synthesis of dyes, pigments, and pharmaceuticals. It serves as a key building block in the production of azo dyes, particularly orange and red colorants used in textiles and printing inks. The compound is also utilized in the manufacture of antioxidants, rubber chemicals, and as a precursor for various organic synthesis reactions in the chemical industry.

2-nitroaniline requires careful handling due to its Acute Tox. 3 classification and DANGER signal word. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection when handling. Work in well-ventilated areas or under fume hoods to avoid inhalation. Prevent skin and eye contact, and ensure emergency washing facilities are readily available. Handle with non-sparking tools and avoid generating dust.

2-nitroaniline should be stored in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Keep containers tightly closed and properly labeled in secondary containment. Store away from strong oxidizing agents, acids, and bases to prevent dangerous reactions. Maintain storage temperatures below 25°C and ensure the storage area is equipped with appropriate fire suppression systems and spill containment measures.

In case of skin contact with 2-nitroaniline, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention. For eye contact, rinse continuously with clean water for at least 15 minutes. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician in all cases of exposure.

2-nitroaniline must be disposed of as hazardous waste according to local, national, and EU regulations. Never discharge into sewers, waterways, or soil due to its environmental toxicity classification (Aquatic Chronic 3). Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities should be collected in appropriate containers, properly labeled, and stored in designated hazardous waste areas until professional disposal can be arranged.

2-nitroaniline is classified under ADR Class 6.1 (Toxic substances), Packing Group II, requiring specific transport regulations compliance. It must be packaged in UN-approved containers with appropriate hazard labels and documentation. Transport vehicles need proper placarding, and drivers require ADR certification. The substance should be segregated from food, animal feed, and incompatible chemicals during transport. Ensure emergency response information is available during shipment.

2-nitroaniline is subject to various European regulations including REACH registration requirements and CLP classification as Acute Tox. 3 and STOT RE 2. While not currently listed as an SVHC substance, it requires safety data sheets and appropriate labeling with GHS06 and GHS08 pictograms. Industrial users must comply with occupational exposure limits and environmental discharge restrictions under various EU directives governing chemical safety and environmental protection.
