Ethanol, 2,2'-[[4-[(2,6-dibromo-4-nitrophenyl)azo]phenyl]imino]bis-, diacetate (ester) (EDD)

CAS Registry Number 55619-18-6

What is it?

Ethanol, 2,2'-[[4-[(2,6-dibromo-4-nitrophenyl)azo]phenyl]imino]bis-, diacetate (ester), also known as EDD, is an industrial chemical.

EDD has previously been reported to be used as a colorant dye.
Small quantities of EDD are believed to be in commerce; however, there is no recent information on manufacturing, importation or use of this substance.

Prior to assessment, EDD 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.

EDD 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.
EDD 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.

The Government of Canada has conducted a science-based evaluation of EDD called a screening assessment.
Results of the final assessment indicate that although EDD may remain in the environment for a long time, the substance is not expected to accumulate in organisms.
Furthermore, the amount of EDD 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 EDD is not entering the environment in a quantity or under conditions that constitute a danger to the environment.

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.

Since EDD 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.
