Chemical Properties
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
Diphenylguanidine is a rubber sensitizer which can
induce immediate-type reactions and delayed-type contact allergy. It was formerly contained in "carbamix".
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 building industries.
Uses
1,3-Diphenylguanidine is used as pharmaceutical intermediate.
Uses
N,N'-Diphenylguanidine is a primary standard for acids; aeeelerator for the vulcanization of rubber for use with thiazoles and sulfenamides; complexing agent
in the deteetion of metals and organie bases.
Definition
ChEBI: 1,3-diphenylguanidine is guanidine carrying a phenyl substituent on each of the two amino groups. It is used as an accelerator in the rubber industry. It has a role as an allergen.
Flammability and Explosibility
Nonflammable
