SECTION 10: Stability and reactivity
Reactivity
Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides. Reacts violently with strong oxidants. Reacts with hypochlorites. This produces explosive chloroamines. Reacts with acids, acid anhydrides, acid chlorides and halogens. Attacks plastic and rubber.
Chemical stability
no data available
Possibility of hazardous reactions
3,5-XYLIDINE ignites on contact with fuming nitric acid (NTP, 1992). Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Conditions to avoid
no data available
Incompatible materials
Strong oxidizers, hypochlorite bleaches Xylidines
Hazardous decomposition products
When heated to decomp, xylidines emit highly toxic fumes. xylidines
SECTION 11: Toxicological information

- Inhalation: no data available
- Dermal: no data available
Skin corrosion/irritation
no data available
Serious eye damage/irritation
no data available
Respiratory or skin sensitization
no data available
Germ cell mutagenicity
no data available
Carcinogenicity
A3; Confirmed animal carcinogen with unknown relevance to humans. Xylidine (mixed isomers)
Reproductive toxicity
no data available
STOT-single exposure
Exposure at high levels could cause lowering of consciousness. Exposure at high levels could cause formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.
STOT-repeated exposure
The substance may have effects on the blood. This may result in anaemia.
Aspiration hazard
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Oryzias latipes - 35 mg/L - 24 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - no data - 2.2 mg/L - 48 h.
- Toxicity to algae: EC50 - no data - 29 mg/L - 72 h.
- Toxicity to microorganisms: no data available
Persistence and degradability
3,5-Xylidine, initially present at 20 mg/l, was 53% degraded in 6 hours using an activated sludge inoculum under aerobic conditions(1). E. coli converted 3,5-xylidine to the corresponding (phenylazo)naphthol in the presence of nitrate with this reaction proceeding within 24 hours(2).
Bioaccumulative potential
An estimated BCF value of 26 was calculated for 3,5-xylidine(SRC), using an estimated log Kow of 2.2(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 3,5-xylidine can be estimated to be about 120(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that 3,5-xylidine has high mobility in soil(SRC). However, anilines are expected to bind stongly to humus or soil organic matter in soils due to the high reactivity of the aromatic amino group(3,4). Low adsorption is observed at a neutral pH with pure clay minerals or soils for substituted anilines(4).
Other adverse effects
no data available
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.
