The Uses of 2,4'-DIAMINODIPHENYLMETHANE

2',4-Bis(aminophenyl)methane is an analog of 4,4'-Methylenedianiline (M304180) and is used in the manufacturing of resin enamel coating materials for copper wires.

General Description

Leaflets.

Reactivity Profile

2,4'-DIAMINODIPHENYLMETHANE is readily oxidzable. Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: 2,4'-DIAMINODIPHENYLMETHANE emits toxic fumes when heated to decomposition. It may be toxic upon inhalation or skin contact.

Fire Hazard

Flash point data for 2,4'-DIAMINODIPHENYLMETHANE are not available. 2,4'-DIAMINODIPHENYLMETHANE is probably combustible.

Safety Profile

Suspected carcinogen. Moderately toxic by subcutaneous route. When heated to decomposition it emits toxic fumes of NOx.
