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

  1. Dye & Pigment Synthesis:
    • Intermediate for ​azo dyes and colorants.
  2. Pharmaceuticals:
    • Building block in drug synthesis (e.g., bioactive molecules).
  3. 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.
