The compound exhibits typical aromatic characteristics with melting and boiling points consistent with substituted anilines. Its stability can be affected by light and heat, requiring appropriate storage conditions to maintain product integrity.

2-chloro-4-nitroaniline serves primarily as an intermediate in pharmaceutical and dye manufacturing. It is commonly used in the synthesis of various organic compounds, particularly in the production of azo dyes and pharmaceutical active ingredients. The compound also finds applications in research and development laboratories for chemical synthesis and as a building block for more complex molecular structures in fine chemical manufacturing.

2-chloro-4-nitroaniline requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation. The compound is classified as Acute Tox. 4, requiring precautions to prevent skin contact, ingestion, or inhalation. Wash hands thoroughly after handling and avoid eating or drinking in work areas.

2-chloro-4-nitroaniline should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep away from incompatible materials such as strong oxidizing agents, acids, and bases. The storage area should be secure and accessible only to trained personnel. Maintain proper labeling with hazard information and ensure containers are in good condition to prevent leaks or contamination.

In case of skin contact with 2-chloro-4-nitroaniline, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist.

2-chloro-4-nitroaniline must be disposed of as hazardous chemical waste according to local and national environmental regulations. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Never dispose of this compound in regular trash, down drains, or into the environment due to its toxicity and environmental persistence. Maintain proper documentation of disposal activities and ensure compliance with all applicable waste management regulations.

2-chloro-4-nitroaniline is classified under ADR Class 6.1 (toxic substances), Packing Group III for transportation. Packages must be properly labeled with appropriate hazard labels and UN identification numbers. Transport should comply with dangerous goods regulations including proper documentation, vehicle placarding, and driver certification. Use appropriate packaging that meets UN specification requirements and ensure proper segregation from incompatible materials during transport.
