10.2 Chemical stabilityHydrazobenzene (10 ug/L) in dilute aqueous solution was found to be unstable with less than 10% remaining for longer than one day of preservation (in the dark) under any of the conditions tested (ie, room temperature or 4°C at pH 2,7, or 10 and with or without chlorine).
10.3 Possibility of hazardous reactions1,2-DIPHENYLHYDRAZINE is a mild reducing agent. Incompatible with strong oxidizing agents, strong acids, acid chlorides and acid anhydrides. Interaction with perchloryl fluoride in the presence of a dilutent below 0°C has caused separation of explosive solids. Is readily oxidized by nitric acid, silver nitrate or permanganate. Is reduced under alkaline conditions .

12.Ecological information 12.1 Toxicity- Toxicity to fish: LC50 Lepomis macrochirus (bluegill) 1.2 mg/L/24 hr (static bioassay, total water hardness 28-44 mg/L calcium carbonate, pH 6.7-7.4, oxygen concn 5.3-7.0 mg/L)
- Toxicity to daphnia and other aquatic invertebrates: LC50 Daphnia magna (water flea) 8.1 mg/L/24 hr /Conditions of bioassay not specified
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
1,2-Diphenylhydrazine is degraded by sludge microorganisms(1). Using a static screening test, 1,2-diphenylhydrazine was inoculated with domestic wastewater and incubated for 7 days followed by 3 weekly subcultures (totaling 28 days of incubation); degradation of 1,2-diphenylhydrazine at 5 mg/l was reported as 80, 73, 66, and 77% for the original, first, second, and third subculture. Degradation of 1,2-diphenylhydrazine at 10 mg/l was reported as 72, 55, 40, and 40% for the original, first, second, and third subculture(2). This pattern was believed to indicate a process of initially significant degradation with gradual adaptation followed by a deadaptive process(2).
12.3 Bioaccumulative potentialThe weighted average bioconcentration factor for 1,2-diphenylhydrazine was reported to be 29 for the edible portions of fish and shellfish consumed by Americans(1). According to a classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC)
12.4 Mobility in soilThe Koc of 1,2-diphenylhydrazine is estimated as approximately 950(SRC), using a measured log Kow of 2.94(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,2-diphenylhydrazine has low mobility in soil(SRC).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
