10.3 Possibility of hazardous reactions
4-CHLORO-O-TOLUIDINE is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. . A halide- and amine-substituted aromatic compound. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Carcinogenicity
Evaluation: There is sufficient evidence for the carcinogenicity of para-chloro-ortho-toluidine hydrochloride in experimental animals. There is limited evidence for the carcinogenicity of para-chloro-ortho-toluidine in humans. In formulating the overall evaluation, the Working Group took note of the fact that any salt of para-chloro-orthotoluidine with a strong acid can be expected to behave chemically in a manner similar to the hydrochloride salt in solution and in vivo. Overall evaluation: para-Chloro-ortho-toluidine and its strong acid salts are probably carcinogenic to humans (Group 2A).

12.2 Persistence and degradability
5 ppm of 14C labeled 4-chloro-o-toluidine was added to soil (pH 7.5, and organic matter, sand, silt, and clay contents of 3.4, 36.6, 28.2, and 35.2%, respectively); nearly 20% of the added 4-chloro-o-toluidine was metabolized to CO2 over a period of 40 days under aerobic conditions(1). Evolution of CO2 from the ring-labelled compound gives evidence for biologically mediated ring cleavage. Autoclaved soil control samples with added 4-chloro-o-toluidine did not produce CO2(1). Incubation of 4-chloro-o-toluidine with aniline oxidase or L-3 peroxidase obtained from the soil fungus Geotrichum candidum resulted in the formation of 2,2'-dimethyl-4,4'dichloroazobenzene through polymerizing transformations of the original compound(2). 4-Chloro-o-toluidine from a petrochemical industrial process wastewater at an initial concentration of 110 mg/l with activated sludge as an inoculum and a one day acclimation period gave 16% removal by measuring COD(Mn) and 7% removal of TOC after a 24 hour period under aerobic conditions(3). This compound was considered to be non-biodegradable using this test(3). Gas chromatography however, used to measure biodegradation during this same 24 hour period, showed better degradability of 4-chloro-o-toluidine suggesting that structural breakdown of this compound occurs prior to oxidation of carbon into carbon dioxide(3). 0% biodegradation of 4-chloro-o-toluidine was shown via BOD in a 2 week experiment using activated sludge as an inoculum and with 4-chloro-o-toluidine present at 100 mg/ml(4).
12.3 Bioaccumulative potential
Bioconcentration of 4-chloro-o-toluidine was measured in carp over a 6 week time period. At concentrations of 0.34 mg/ml and 0.034 mg/ml 4-chloro-o-toluidine, BCF values of 7.7-12 and <35 respectively, were reported(1). These values suggest that bioconcentration of 4-chloro-o-toluidine in aquatic organisms is not an important fate process for this compound(SRC).
12.4 Mobility in soil
The Koc for 4-chloro-o-toluidine was estimated as 410(SRC), using a recommended regression-derived equation(1) and an estiamted log Kow of 2.27(2,SRC). According to a suggested classification scheme(3), this estimated Koc value suggests that 4-chloro-o-toluidine has moderate mobility in soil(SRC). 14C labelled 4-chloro-o-toluidine was added to autoclaved soil (pH 7.5, and organic matter, sand, silt, and clay contents of 3.4, 36.6, 28.2, and 35.2%, respectively) and incubated for several weeks; 12.2% of the radioactive label was removed as volatiles, 25% was recovered in a Soxhlet extract, and 55.1% of the radioactive label was obtained after Soxhlet extraction using Bleidner distillation (bound residue fraction)(4). This suggests that a significant portion of the 4-chloro-o-toluidine is bound strongly by this soil(4). Over a 24 hour time period, 34% of applied 4-chloro-o-toluidine was found in the bound residue fraction(5). Binding due to the high reactivity of the aromatic amino group to humus or soil organic matter rather than to clay particles is proposed as a reason for the soil binding ability of anilines(4,5). Low adsorption is observed at a neutral pH with pure clay minerals or soils for substituted anilines(5).

13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
