SECTION 10: Stability and reactivity
Reactivity
Reacts with strong oxidants.
Chemical stability
Quite stable upon storage hydroquinone ethers
Possibility of hazardous reactions
Dust explosion possible if in powder or granular form, mixed with air.1,4-DIMETHOXYBENZENE is an ether. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Danio rerio (previous name: Brachydanio rerio) - 127 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 52 mg/L - 48 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 50.5 mg/L - 72 h.
- Toxicity to microorganisms: NOEC - activated sludge of a predominantly domestic sewage - 100 mg/L - 28 d. Remarks:Respiration rate.
Persistence and degradability
Eight days were required to completely degrade hydroquinone dimethyl ether using a mixed soil population, as measured by loss of UV absorbance (indicates ring cleavage)(1). Hydroquinone dimethyl ether, when present as the sole carbon source, was not utilized by a bacterial soil isolate for growth over 30 days(2).
Bioaccumulative potential
An estimated BCF value of 20 was calculated for hydroquinone dimethyl ether(SRC), using an experimental log Kow of 2.03(2) and a recommended regression-derived equation(1). This BCF value suggests that hydroquinone dimethyl ether will not bioconcentrate in aquatic organisms(SRC).
Mobility in soil
Based on an experimental log Kow of 2.03(1), the Koc of hydroquinone dimethyl ether is estimated as approximately 300 using a regression-derived equation(2,SRC). According to a suggested classification scheme(3), this estimated Koc value suggests that hydroquinone dimethyl ether will have moderate mobility in soil(SRC).
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.
