Diaminodiphenyl ether (DADPE, C₁₂H₁₂N₂O) is an important aromatic amine compound featuring two amino groups attached to a diphenyl ether structure. This white to pale yellow crystalline solid has a molecular weight of 200.24 g/mol and melts at 135-137°C. It exhibits limited solubility in water but dissolves well in organic solvents like ethanol, acetone, and dimethylformamide.

o-Aminophenol (C₆H₇NO) is an important aromatic organic compound with both amine (-NH₂) and hydroxyl (-OH) functional groups in the ortho position on a benzene ring. This white to light brown crystalline solid has a molecular weight of 109.13 g/mol and melts at 170-174°C. It exhibits moderate solubility in water (1.4 g/100 mL at 25°C) and better solubility in organic solvents like ethanol and ether.
