Propanenitrile, 3-[[4-[(2,6-dibromo-4-nitrophenyl)azo]phenyl]ethylamino]- (Disperse Orange 61)
CAS Registry Number 55281-26-0
What is it?
- Propanenitrile, 3-[[4-[(2,6-dibromo-4-nitrophenyl)azo]phenyl]ethylamino]-, also known as Disperse Orange 61, is an industrial chemical.
How is it used?
- Disperse Orange 61 is used as a colorant dye, mainly in textiles and fabric.
- Based on the most recent data available, Disperse Orange 61 is not manufactured in Canada but is imported into Canada.
Why did the Government of Canada assess it?
- Prior to assessment, Disperse Orange 61 was identified as a potential concern to the environment based on information regarding possible persistence, accumulation in organisms and potential to cause harm to organisms.
How is it released to the environment?
- Disperse Orange 61 may be released to the environment during industrial processes and consumer use.
- Upon its release, most of the substance is expected to end up in solid waste disposal sites. A significant proportion is also estimated to be released to sewer water.
- Disperse Orange 61 may remain in the environment for a long time when released. However, data suggests that the substance does not significantly accumulate in or directly harm organisms.
What are the results of the assessment?
- The Government of Canada has conducted a science-based evaluation of Disperse Orange 61 called a screening assessment.
- Results of assessment indicate that although Disperse Orange 61 may remain in the environment for a long time, the substance is not expected to accumulate in organisms.
- Furthermore, the quantity of Disperse Orange 61 that may be released to the environment is below the level expected to cause harm to organisms.
- The Government of Canada has therefore determined that Disperse Orange 61 is not entering the environment in a quantity or under conditions that constitute a danger to the environment.
What is the Government of Canada doing?
- Based on the conclusion of the final screening assessment, no further action is required for this substance.
- The final screening assessment was published on August 22, 2009.
What could Canadians do?
- Since Disperse Orange 61 is not presently a concern for the environment or human health, Canadians do not currently need to take any specific actions with respect to this chemical.
