Specific Hazards Arising from the Chemical

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)

Advice for firefighters

Use water spray, powder, foam, carbon dioxide.

SECTION 6: Accidental release measures

Personal precautions, protective equipment and emergency procedures

Persistence and degradability

no data available

Bioaccumulative potential

A range of BCF values of 1.3 to 4.6 were measured for carp exposed to 2 ppm 2,4-diaminoanisole over the course of a 6 week incubation period(1). According to a classification scheme(2), this BCF range suggests bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2,4-diaminoanisole can be estimated to be 53(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,4-diaminoanisole is expected to have high mobility in soil. 2,4-Diaminoanisole is a weak base with an estimated pKa of 5.15(SRC), calculated by a method based on linear free energy relationships and perturbed molecular orbital theory(3). This estimated pKa indicates that 2,4-diaminoanisole will partially exist in the protonated form in acidic moist soils and cations generally adsorb to soils more strongly than their neutral counterparts(4). Moreover, anilines (aromatic amines) are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(5,6), suggesting that the mobility of 2,4-diaminoanisole may be much lower in some soils than indicated by the estimated Koc value(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.

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.
