| Usage | An amino substituted benzene used in the manufacture of dyes. Potential use in sensitive immunosensor for cancer biomarker. |
| General Description | Colorless monoclinic crystals if pure; technical grade brownish-yellow crystals or a sandy brown solid. Used in manufacture of dyes, photography, organic synthesis. |
| Air & Water Reactions | Soluble in water [Hawley]. Melting point 219 F. Flash point 277 F. Toxic by skin absorption, inhalation or ingestion. Even as a solid will spot downwind area brown/purple (Roger Patrick, DuPont Engineer). |
| Reactivity Profile | o-Phenylenediamine a weak aromatic amine base neutralizes acids in exothermic reactions to form salts. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Darkens on exposure to air (Roger Patrick, DuPont Engineer). |
| Fire Hazard | Flash point data for o-Phenylenediamine are not available. o-Phenylenediamine is probably combustible. |
