Para-toluidine has a distinct winelike odour.
Key Characteristics of Para-Toluidine
Para-toluidine, also known as p-toluidine, is an organic chemical compound with several notable physical attributes that contribute to its identification and handling. While its odour is a primary sensory characteristic, other properties are equally important:
- Olfactory Profile: The most prominent volatile characteristic of para-toluidine is its winelike odour. This specific aroma helps in its recognition.
- Physical Form: In its pure state, para-toluidine typically appears as white, lustrous plates or leaflets. These crystalline forms are a hallmark of its solid state.
- Environmental Stability: When exposed to air, the white crystals of para-toluidine tend to turn dark. This change suggests a reaction or degradation process occurs upon atmospheric exposure, which is an important consideration for storage and handling.
Summary of Para-Toluidine's Properties
For a quick reference, here's a summary of the key physical properties:
| Property | Description |
|---|---|
| Odour | Winelike |
| Appearance | White, lustrous plates or leaflets |
| Stability | Turns dark on exposure to air |
Understanding these characteristics, particularly its unique winelike smell, is essential for anyone working with or identifying para-toluidine.
