2,4-dinitroaniline

2,4-dinitroaniline is an organic chemical compound with the molecular formula C6H5N3O4 and CAS number 97-02-9. This aromatic amine features two nitro groups (-NO2) attached to positions 2 and 4 of an aniline ring. With a molecular weight of 183.12 g/mol, it appears as a yellow to orange crystalline solid. The compound is classified as highly toxic and poses significant health and environmental hazards, requiring careful handling in industrial applications.

2,4-dinitroaniline is a yellow to orange crystalline solid at room temperature with a characteristic aromatic odor. The compound has a molecular weight of 183.12 g/mol and is poorly soluble in water but soluble in organic solvents like alcohol and acetone. It exhibits stability under normal conditions but can decompose when heated, releasing toxic nitrogen oxides. The presence of nitro groups makes it electron-deficient and reactive toward nucleophiles.

2,4-dinitroaniline is primarily used as an intermediate in the synthesis of dyes, pigments, and pharmaceuticals. It serves as a precursor for manufacturing various organic compounds in the chemical industry, particularly in the production of azo dyes and other colorants. The compound is also utilized in research and development applications for organic synthesis. Its reactive nitro groups make it valuable for creating more complex molecular structures through reduction or substitution reactions.

2,4-dinitroaniline requires strict safety measures due to its high toxicity classification (Acute Tox. 1 and 2). Personnel must wear full personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Avoid skin contact and ingestion completely. Emergency shower and eyewash stations should be readily accessible. Only trained personnel should handle this substance following established safety protocols.

2,4-dinitroaniline must 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 designated chemical storage areas. Avoid storage near strong acids, bases, and reducing agents due to potential reactions. The storage area should have appropriate containment measures for spills and be accessible only to authorized personnel. Regular inspection of containers for integrity is essential to prevent leaks.

2,4-dinitroaniline exposure requires immediate action due to its high toxicity. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, flush with clean water for 15 minutes while holding eyelids open. If ingested, do not induce vomiting and seek immediate medical help. Always consult a physician after any exposure incident.

2,4-dinitroaniline disposal must comply with local and national hazardous waste regulations due to its toxic and environmentally harmful properties. The substance cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment facilities. Contact licensed waste disposal companies for proper collection and destruction. Contaminated materials, containers, and protective equipment must also be treated as hazardous waste. Maintain proper documentation of all disposal activities for regulatory compliance.

2,4-dinitroaniline is classified under ADR as Class 6.1 (toxic substances), Packing Group II, indicating significant transport hazards. Packages must bear proper hazard labels including GHS06, GHS08, and GHS09 pictograms with 'Danger' signal word. Transportation requires appropriate packaging specifications, proper documentation, and trained personnel. Vehicles must carry emergency response information and appropriate firefighting equipment. Compliance with international dangerous goods regulations (ADR/IMDG/IATA) is mandatory for all transport modes.

2,4-dinitroaniline is subject to extensive chemical regulations including REACH registration requirements in Europe and CLP classification as a hazardous substance. The compound's classification includes multiple acute toxicity categories and environmental hazards, triggering various regulatory obligations for manufacturers and users. Companies must maintain safety data sheets, conduct risk assessments, and implement appropriate risk management measures. Regular monitoring of regulatory updates is essential as restrictions may evolve based on ongoing safety evaluations.
