2,4-dinitroaniline

2,4-dinitroaniline is an organic chemical compound with the molecular formula C6H5N3O4 and CAS number 97-02-9. It belongs to the nitroaniline family, characterized by an aniline structure with two nitro groups positioned at the 2 and 4 positions on the benzene ring. With a molecular weight of 183.12 g/mol, this compound is classified as highly hazardous due to its acute toxicity and potential for causing specific target organ toxicity upon repeated exposure.

2,4-dinitroaniline typically appears as yellow to orange crystalline solid at room temperature. The compound has limited water solubility due to its aromatic structure and nitro substituents. It exhibits stability under normal conditions but may decompose when exposed to high temperatures or strong reducing agents. The presence of electron-withdrawing nitro groups significantly affects its chemical reactivity and makes it less basic compared to unsubstituted aniline.

2,4-dinitroaniline is primarily used as an intermediate in the synthesis of dyes, pigments, and other organic compounds in the chemical industry. It serves as a precursor for manufacturing various azo dyes and serves in pharmaceutical synthesis pathways. The compound is also utilized in research and analytical chemistry applications. Its specific chemical structure makes it valuable for producing specialized chemical products requiring nitroaniline derivatives.

2,4-dinitroaniline requires strict safety measures due to its high acute toxicity classification. Personnel must wear appropriate 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 exposure. Avoid skin contact and ingestion completely. Emergency eyewash stations and safety showers should be readily accessible, and all handling procedures must follow established chemical safety protocols.

2,4-dinitroaniline must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly sealed and store separately from strong reducing agents, bases, and oxidizing substances. The storage area should be equipped with appropriate containment measures and access should be restricted to trained personnel only. Regular inspection of containers for damage or leakage is essential to maintain safe storage conditions.

Immediate action is critical due to the compound's high toxicity. For skin contact, remove contaminated clothing and flush affected area with plenty of water for at least 15 minutes. If inhaled, move person to fresh air immediately and seek medical attention. In case of eye contact, rinse thoroughly with water for several minutes. If ingested, do not induce vomiting and seek immediate medical care. Always consult a physician and provide the safety data sheet.

2,4-dinitroaniline disposal must comply with local and European waste regulations due to its hazardous classification. The compound cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment. Contact licensed waste disposal companies experienced in handling toxic organic compounds. Incineration at high temperatures in approved facilities is typically the preferred disposal method. Always maintain proper documentation and follow waste tracking requirements throughout the disposal process.

2,4-dinitroaniline is classified under ADR as Class 6.1 (toxic substances), Packing Group II, indicating significant transport hazards. Packages must bear appropriate UN identification numbers and hazard labels including GHS06, GHS08, and GHS09 pictograms with 'Danger' signal word. Only authorized carriers trained in dangerous goods transport should handle shipments. Proper documentation including transport documents and emergency response information must accompany all shipments according to ADR regulations.

2,4-dinitroaniline is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification standards. The compound's high acute toxicity and environmental hazard classifications trigger specific handling, labeling, and documentation obligations. While not currently listed as an SVHC substance, its toxic properties require compliance with occupational exposure limits and environmental protection measures. Users must maintain safety data sheets and follow all applicable national chemical safety regulations.
