SECTION 10: Stability and reactivity
10.1 Reactivity
Decomposes on heating. This produces toxic fumes including aniline and nitrobenzene. The solution in water is a weak acid. May explode on vacuum distillation.
10.2 Chemical stability
Very stable toward acids & alkalies, & toward oxidation & reduction; it forms stable metallic salts
10.3 Possibility of hazardous reactions
Dust explosion possible if in powder or granular form, mixed with air.The triazoles are a group of highly explosive materials that are sensitive to heat, friction, and impact. Sensitivity varies with the type substitution to the triazole ring. Metal chelated and halogen substitution of the triazol ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives.

SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: LC50 - Danio rerio (previous name: Brachydanio rerio) - 180 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - other aquatic crustacea: Daphnia galeata - 15.8 mg/L - 48 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 75 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - 940 mg/L - 3 h. Remarks:Respiration rate.
12.2 Persistence and degradability
1,2,3-benzotriazole was biol stable as source of org c for activated sludge inoculum.
12.3 Bioaccumulative potential
An estimated BCF of 2.5 was calculated for 1,2,3-benzotriazole(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
12.4 Mobility in soil
The Koc of 1,2,3-benzotriazole is estimated as 145(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), these estimated Koc values suggests that 1,2,3- benzotriazole is expected to have high mobility in soil. However, mobility of 1,2,3-benzotriazole will be affected by pH(2): the pKa of benzotriazole is 8.37(4), indicating that this compound will exist in the cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts.
12.5 Other adverse effects
no data available
SECTION 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.
