SECTION 10: Stability and reactivity
Reactivity
Decomposes on burning. This produces toxic fumes. The solution in water is a medium strong base.
Chemical stability
no data available
Possibility of hazardous reactions
1,3-DIPHENYLGUANIDINE behaves as an amine. 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. This chemical is incompatible with strong oxidizers. (NTP, 1992)
Conditions to avoid

Incompatible materials

Hazardous decomposition products

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Pimephales promelas - 4.2 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 17 mg/L - 48 h.
- Toxicity to algae: EC50 - Desmodesmus subspicatus (previous name: Scenedesmus subspicatus) - 2.6 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - activated sludge, industrial - 147 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
N,N'-Diphenylguanidine, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). N,N'-Diphenylguanidine present at 20 mg/L in river water or sea water was 18% and 9% degraded, respectively, after a 3-day cultivation period(2). Therefore this compound is not expected to biodegrade rapidly.
Bioaccumulative potential
BCFs of <2 and <20 were measured for N,N'-diphenylguanidine(SRC) using orange-red killifish (Oryzias latipes) which were exposed over a 6-week period(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for N,N'-diphenylguanidine can be estimated to be 5,900(SRC). According to a classification scheme(2), this estimated Koc value suggests that N,N'-diphenylguanidine is expected to be immobile in soil. The pKa of N,N'-diphenylguanidine is 10.12(3), indicating that this compound will primarily exist in the protonated form in the environment and cations generally adsorb more strongly to organic carbon and clay than their neutral counterparts(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.
