Carcinogenicity
The Human Health Assessment Group in EPA's Office of Health and Environmental Assessment has evaluated dimethylaminoazobenzene for carcinogenicity. According to their analysis, the weight-of-evidence for dimethylaminoazobenzene is group B2, which is based on no evidence in humans and sufficient evidence in animals. As a group B2 chemical, dimethylaminoazobenzene is considered to be probably carcinogenic to humans.
Reproductive toxicity
No information is available on the reproductive or developmental effects of 4-dimethylaminoazobenzene in humans. Animal studies have reported birth defects in the offspring of mice exposed to 4-dimethylaminoazobenzene.
STOT-single exposure
The substance is irritating to the eyes, skin and respiratory tract.
STOT-repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. This substance is possibly carcinogenic to humans.
Aspiration hazard
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: no data available
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
12.2 Persistence and degradability
Recovery of 0.29 ppm N,N-dimethyl-p-(phenylazo)aniline incubated with an original culture of settled domestic wastewater after 7 days was at trace levels and it was not detected following 1st, 2nd, and 3rd subcultures after 7 days each(1).
12.3 Bioaccumulative potential
Using a reported log octanol/water partition coefficient of 4.58(1), an estimated BCF of 1780 was calculated(2,SRC). Based on this estimated BCF, N,N-dimethyl-p-(phenylazo)aniline should bioconcentrate in aquatic organisms(SRC).
12.4 Mobility in soil
Using a reported log octanol/water partition coefficient of 4.58(1), an estimated Koc of 7390 was calculated(2,SRC). Based on this estimated Koc, N,N-dimethyl-p-(phenylazo)aniline should adsorb to soils and sediment. Since N,N-dimethyl-p-(phenylazo)aniline has a pKa of 3.226 at 25 deg C(3), and it exists partially as a cation, the extent of its adsorption to soils and sediments may be affected by the pH of the medium.
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.
