SYMPTOMS: Symptoms of exposure to this chemical may include skin sensitization reactions, eye irritation and injury, skin irritation, dermatitis, blackened skin and bronchial asthma. Other symptoms may include allergic skin reactions, irritation of the mucous membranes, nose, throat and lungs, coughing, burning sensation, runny nose, sore throat, methemoglobinemia, cyanosis, headache, dizziness, drowsiness, mental confusion, pulmonary edema, kidney and liver damage, central nervous system effects and conjunctivitis. Eye contact may cause discomfort, tearing, blurring of vision, reddening, partial clouding of the cornea and swelling of the eye and surrounding tissue. Dysuria and eosinophiluria may also occur. Exposure may also result in respiratory tract irritation. ACUTE/CHRONIC HAZARDS: This compound is harmful if inhaled, swallowed or absorbed through the skin. It causes irritation of the eyes, skin, mucous membrane and respiratory tract. When heated to decomposition, this compound emits irritating and/or toxic gases and fumes of carbon monoxide, carbon dioxide and oxides of nitrogen. (NTP, 1992)

This chemical is combustible. Dust may form explosive mixtures in air (NTP, 1992)

Use water spray, powder.

Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Thermal hazards

Decomposes on burning. This produces toxic fumes including nitrogen oxides. Reacts with strong oxidants.

Unstable in air

FIRE POINT: 175 DEG C.1,3-PHENYLENEDIAMINE an aromatic amine, neutralizes acids, acid chlorides, acid anhydrides and chloroformates in exothermic reactions to form salts. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Incompatible with oxidizing agents (NTP, 1992).

no data available

STABILITY: This compound is sensitive to light. It turns red on exposure to air. This compound darkens on storage. Moist air and excess heat cause it to degrade. Solutions of this chemical in water, DMSO, 95% ethanol or acetone should be stable for 24 hours under normal lab conditions.REACTIVITY: This compound is incompatible with oxidizing agents. It is also incompatible with acids, acid chlorides, acid anhydrides and chloroformates. (NTP, 1992)

When heated to decomp, it emits toxic fumes of nitrogen oxides.

Aspiration hazard

• Toxicity to fish: LC50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - 512 mg/L - 96 h.
• Toxicity to daphnia and other aquatic invertebrates: LC50 - Gammarus fasciatus - 4.6 mg/L - 96 h.
• Toxicity to algae: NOEC - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 0.915 mg/L - 96 h.
• Toxicity to microorganisms: 30% reduction in respiration rate - activated sludge of a predominantly industrial sewage - 100 mg/L - 30 min. Remarks:Respiration rate.

1,3-Benzenediamine was observed to degrade 60% after 5 days at concn levels of 25 to 30 ppm using an acclimated activated sludge inoculum(1). However at 50 ppm 1,3-benzenediamine was reported to be toxic to 3 unacclimated activated sludges(2). Soil microflora did not cleave the benzene ring of 1,3-benzenediamine in 64 days(3). 1,3-Benzenediamine, present at an initial concn of 100 mg/l, reached 2% of its theoretical BOD in 4 weeks using an activated sludge inoculum(4).

An estimated BCF value of 0.33 was calculated for 1,3-benzenediamine(SRC), using an estimated log Kow of -0.33(1) and a recommended regression-derived equation(2). BCF values of 1.3 to 4.6 and <1.6 to 24 were measured for 1,3-benzenediamine in carp at 2 and 0.2 mg/l, respectively(3). According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms is low(SRC).

The Koc of 1,3-benzenediamine is estimated as approximately 16(SRC), using a measured log Kow of -0.33(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 1,3-benzenediamine is expected to have very high mobility in soil(SRC). However, 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); therefore, mobility may be much lower in some soils(SRC).
