Most important symptoms/effects, acute and delayed
SYMPTOMS: Exposure to this material can cause local irritation, headache, cyanosis, jaundice, methemoglobinemia, weight loss, anemia, weakness and irritability. ACUTE/CHRONIC HAZARDS: This chemical is a skin irritant and an allergen. It can be absorbed through the skin and upon inhalation of dust. Toxic fumes are evolved when this material is heated to decomposition or upon contact with acid or acid fumes. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
The disposition and metabolism of 14C-labeled 4-chloro-2-nitroaniline (CNA) was studied in male F344 rats following oral or intravenous (iv) administration. The gastrointestinal absorption of CNA was found to be near complete and was not affected by the dose in the range studied (0.788-78.8 mumol/kg). Following either oral or iv administration, CNA was rapidly distributed throughout the tissues and showed no marked affinity for any particular tissue. [14C]CNA was rapidly cleared by metabolism and excretion in urine and to a lesser extent in feces...
SECTION 5: Firefighting measures
Suitable extinguishing media
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.

Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Prevent product from entering drains. Sweep up and shovel into suitable containers for disposal.
SECTION 7: Handling and storage

Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Possibility of hazardous reactions
4-CHLORO-2-NITROANILINE forms explosive products on reaction with nitric acid. Can react with oxidizing agents. (NTP, 1992)
Conditions to avoid
no data available
Incompatible materials
In a large scale-up of the method for preparing 4-chloro-2,6-dinitroaniline by reacting nitric acid with 4-chloro-2-nitroaniline, an unexpected strong evolution of heat was experienced. The exotherm was found due to the simultaneous formation of two explosive products: the isomer 2-chloro-4,6-dinitroaniline & also 4-chloro-3,6-dinitrophenyldiazonium-2-oxide.
Hazardous decomposition products
When heated to decomposition ... emits toxic vapors of /nitrogen oxides and hydrogen chloride/.

Persistence and degradability
AEROBIC: 4-Chloro-2-nitroaniline, present at 100 ppm, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 ppm and the Japanese MITI test(1).
Bioaccumulative potential
A 6 week bioconcentration study obtained BCF values of 7.5-13.2 and 8.0-13.4 in carp (Cyprinus carpio) for concentrations of 4-chloro-2-nitroaniline of 100 and 10 ppb, respectively(1). According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of 4-chloro-2-nitroaniline is estimated as 720(SRC), using a log Kow of 2.72(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4-chloro-2-nitroaniline is expected to have low mobility in soil. Anilines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4,5), suggesting that mobility may be much lower in some soils(SRC). The log Koc of 4-chloro-2-nitroaniline was measured as 2.30 in Yangtze river sediment (37.1% sand, 49.3% silt, 13.6% clay, 1.28% organic carbon, pH 7.44)(6). The log Koc was also measured as 3.68 in modified clay(7). These values give Koc values of 200 and 4800, respectively(SRC).
Other adverse effects

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
