SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces toxic gases including ammonia (see ICSC 0414). Reacts violently with strong oxidants such as ammonium nitrate. This generates fire and explosion hazard. Reacts with acids. This produces toxic gases including hydrogen cyanide. See ICSC 0492.
Chemical stability
Stable when dry
Possibility of hazardous reactions
NON-FLAMMABLE.

- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 3 177 mg/L - 48 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 2.04 g/L - 4 d.
- Toxicity to microorganisms: TT - Pseudomonas putida - 130.6 mg/L - 18 h.
Persistence and degradability
Cyanoguanidine, at 30 mg/l, reached only 2.2% of the theoretical BOD in two weeks using a sludge inoculum(1). Biodegradation of cyanoguanidine was measured in six soils, five collected from Sri Lankan tea plantations and one grassland soil from Highfield, UK; in the near-neutral Highfield soil (pH = 6.8), 10.2 and 41.6% of the cyanoguanidine-N was mineralized after 12 and 60 days, respectively(2). In the other, more acidic soils (pH = 4.0-4.3), only a small percentage of the added cyanoguanidine-N was mineralized to ammonia and nitrate nitrogen; mineralization after 60 days was only 10-25% that of the Highland soil(2). Mineralization was correlated with soil pH but not with organic matter content or total nitrogen(2). Cyanoguanidine, at 20 mg/l was added to flooded sediments; complete degradation was reported within 34-44 weeks for aerobic conditions, while under anaerobic conditions two-thirds of the initial concentration was degraded within 60 weeks(3).
Bioaccumulative potential
BCF values of <0.3 and <3.1 were measured for cyanoguanidine at 2 and 0.2 mg/l, respectively, in carp(1). According to a classification scheme(2), these BCF values suggest that bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of cyanoguanidine is estimated as approximately 6(SRC), using a measured log Kow of -1.15(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that cyanoguanidine has very high mobility in soil(SRC). However, when leaching of cyanoguanidine following mineral fertilization, slurry manuring and decomposition under simulated ground water conditions (silty loam, pH 6.5) was measured in lysimeters(4). After mineral feeding, only 0.6-0.9% of the cyanoguanidine applied in 5 years was leached with the highest leaching rate occurring in October (with 5.6% leached of the added amount)(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.
