Definition
  1. Noun:
    • A chemical compound: "ethylamine" is a colorless, volatile, and flammable organic compound with the formula CH₃CH₂NH₂. It is a primary amine, meaning it has an amino group (-NH₂) attached to an ethyl group (-CH₂CH₃). It is commonly used in organic synthesis, as a precursor to pharmaceuticals, pesticides, and rubber chemicals.
Usage Examples
  • Noun:
    • The chemist synthesized ethylamine from ethanol and ammonia in the laboratory. (The compound was produced through a chemical reaction.)
    • Ethylamine has a strong, fishy odor, similar to ammonia. (The compound's characteristic smell is noted.)
    • Many herbicides and dyes are derived from ethylamine. (The compound serves as a building block in manufacturing.)
Advanced Usage

  • "Ethylamine hydrochloride": a salt form of ethylamine used in laboratory settings.

    • The reaction required ethylamine hydrochloride as a reagent to neutralize the solution. (The salt form was used for stability.)

  • "Ethylamine solution": a mixture of ethylamine dissolved in a solvent, often water or alcohol.

    • A 70% ethylamine solution in water is commonly used in organic synthesis. (The concentration and solvent are specified.)
Variants and Related Words
