Diphenylguanidine is a rubber sensitizer that can induce immediate-type reactions and delayed-type contact allergy. It was formerly contained in “carba mix.” Occupational exposure concerns finished rubber items and the rubber manufacturing industry. The most frequent occupational categories are metal industry, homemakers, health services and laboratories, and the building industry. | [InChIKey]

white or cream powder with a slight odour | [General Description]
White to cream-colored chalky powder. Bitter taste and slight odor. | [Reactivity Profile]
1,3-DIPHENYLGUANIDINE(102-06-7) behaves as an amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. This chemical is incompatible with strong oxidizers. | [Air & Water Reactions]
Sensitive to moisture. Aqueous solutions are strongly alkaline. Insoluble in water. | [Fire Hazard]
This chemical is combustible. | [Description]
