p-Ethoxyaniline (4-Ethoxyaniline)
Chemical Formula: C₈H₁₁NO
Structure: Aniline derivative with an ethoxy group (-OCH₂CH₃) at the para position (4-position) relative to the amino group (-NH₂) on a benzene ring.
Physical Form: Colorless to pale yellow liquid/solid with a mild aromatic odor.
Properties
- Solubility:
- Soluble in ethanol, ether; poorly soluble in water.
- Reactivity:
- Amino group (-NH₂) enables electrophilic substitution reactions.
- Ethoxy group modulates electronic properties of the benzene ring.
- Stability:
- Stable under normal conditions; may darken upon exposure to air/light.
Applications
- Dye & Pigment Synthesis:
- Intermediate for azo dyes and colorants.
- Pharmaceuticals:
- Building block in drug synthesis (e.g., bioactive molecules).
- Chemical Research:
- Reagent in organic synthesis and catalysis studies.
Safety Considerations
- Toxicity: Harmful if ingested or inhaled.
- Handling: Use gloves, ventilation, and avoid direct contact.
Summary:
p-Ethoxyaniline’s dual functional groups (amino and ethoxy) make it a versatile intermediate in dyes, pharmaceuticals, and chemical research. Its reactivity and structural features drive industrial utility, but safe handling is critical.
