2,4-Diaminoanisole sulfate Usage And Synthesis

Chemical Properties

2,4-Diaminoanisole is a needle-like solid.

Uses

2,4-Diaminoanisole sulfate has been used primarily as a component of oxidizing “permanent” hair- and fur-dye formulations. In 1978, about 75% of hair-dye formulations contained 2,4-diaminoanisole orits sulfate. However, a U.S. regulation requiring a warning label on allhair dyes containing 2,4-diaminoanisole or its sulfate was to become effective in April 1980, and the chemicals were voluntarily removed from products before that time (IARC 1982). 2,4-Diaminoanisole also has been used as an intermediate in the production of C.I. basic brown 2, which has been used to dye furs, acrylic fibers, cotton, wool, nylon, polyester, leather, and suede and has been an ingredient of shoe polishes (IARC 1978, 1982).

General Description

Off-white to violet or dark brown powder. Emits toxic fumes of nitrogen oxides and sulfur oxides when heated to decomposition.

Air & Water Reactions

Water soluble. Darkens on exposure to light.

Reactivity Profile

2,4-Diaminoanisole sulfate is weakly acidic. Can react as either an oxidizing agent or reducing agent.

Fire Hazard

Flash point data for 2,4-Diaminoanisole sulfate are not available; however, 2,4-Diaminoanisole sulfate is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by intraperitoneal route. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and SOx. See also other diaminoanisole entries.

Potential Exposure

The principal use of 2,4-diamino-ani- sole (and its salts such as the sulfate) as a component of oxidation (permanent) hair and fur dye formulations. Human exposure to 2,4-diaminoanisole sulfate may possibly occur through skin absorption at chemical and dye production facilities, as well as through dermal contact in persons using hair dyes containing the chemical.

Carcinogenicity

2,4-Diaminoanisole sulfate is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3143 Dyes, solid, toxic, n.o.s. or Dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Incompatible with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. The sulfate may react violently with aluminum and magnesium.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinera- tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed .
