3-chloro-4-nitroaniline

3-chloro-4-nitroaniline is an aromatic amine compound with the molecular formula C6H5ClN2O2 and CAS number 825-41-2. This chemical substance contains both chlorine and nitro functional groups attached to an aniline ring structure, giving it a molecular weight of 172.57 g/mol. It is classified as a highly hazardous chemical with acute toxicity properties and requires careful handling due to its dangerous classification under GHS regulations.

3-chloro-4-nitroaniline is typically a solid crystalline compound at room temperature with a characteristic yellow to orange coloration. As an aromatic amine derivative, it exhibits limited water solubility but dissolves in organic solvents. The presence of both electron-withdrawing groups (chlorine and nitro) on the benzene ring influences its chemical reactivity and stability. Its molecular structure makes it relatively stable under normal conditions but reactive under specific chemical environments.

3-chloro-4-nitroaniline serves primarily as an intermediate in the synthesis of dyes, pigments, and pharmaceuticals. It is commonly used in the production of azo dyes and other colorants for textile and industrial applications. The compound also functions as a building block in organic synthesis for creating more complex chemical structures. Its unique substitution pattern makes it valuable in specialized chemical manufacturing processes requiring specific reactivity profiles.

3-chloro-4-nitroaniline requires strict safety protocols due to its Acute Tox. 1 and 2 classifications. Personnel must wear appropriate PPE including chemical-resistant gloves, safety goggles, and respiratory protection when handling this substance. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. The compound's high toxicity demands immediate medical attention if exposure occurs, and all handling procedures must follow established safety protocols.

3-chloro-4-nitroaniline must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Storage areas should be equipped with appropriate containment measures and emergency response equipment. The compound should be kept away from strong oxidizers and reducing agents that could cause dangerous reactions. Regular inspection of storage containers is essential to detect any signs of degradation or leakage.

Immediate action is critical due to the high acute toxicity of 3-chloro-4-nitroaniline. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes. If inhaled, move the person to fresh air immediately. Seek immediate medical attention for any exposure route, as this compound can cause severe health effects requiring professional medical intervention.

3-chloro-4-nitroaniline disposal must comply with local, national, and EU 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 hazardous waste disposal companies for proper collection and treatment. Incineration at high temperatures in approved facilities is typically the preferred disposal method. All disposal activities must be documented according to waste tracking regulations.

3-chloro-4-nitroaniline is classified as ADR Class 6.1, Packing Group III for transport purposes. This classification identifies it as a toxic substance requiring specific packaging, labeling, and documentation during transportation. Packages must display appropriate hazard labels and proper shipping names. Drivers must possess valid ADR certification for Class 6.1 substances. Transport vehicles require appropriate emergency equipment and documentation, including safety data sheets and emergency response procedures.

3-chloro-4-nitroaniline is subject to comprehensive EU chemical regulations including REACH registration requirements and CLP classification obligations. While not currently listed as an SVHC substance, its high toxicity classification means it falls under strict handling and notification requirements. Industrial users must comply with occupational exposure limits and workplace safety regulations. Import and use may require specific authorizations depending on quantities and applications, particularly in pharmaceutical and dye manufacturing sectors.
