Meaning and Use of Amine

Definition:

1. Organic Chemistry:
   A large class of organic compounds derived from ammonia (NH₃), where one or more hydrogen atoms are replaced by alkyl or aryl groups.
2. Types of Amines:

• Primary Amine: One hydrogen atom replaced (RNH₂).
• Secondary Amine: Two hydrogen atoms replaced (R₁R₂NH).
• Tertiary Amine: All three hydrogen atoms replaced (R₁R₂R₃N).

1. Biological Role:
   Amines are found in vital biomolecules, such as amino acids and neurotransmitters, and play crucial roles in biological functions.

Use in Contexts:

• Amines are widely used in pharmaceuticals, dyes, agriculture, and the synthesis of polymers and other chemicals.

Origin of Amine

The term amine originated in the mid-19th century as the study of organic compounds advanced.

• Etymology:
  Derived from “ammonia” and the suffix “-ine”, which is often used for organic compounds.

The earliest recorded usage appeared in 1852 in the Quarterly Journal of the Chemical Society, which discussed the chemical properties of amines in relation to ammonia and hydrocarbons.

Examples of Amine Usage
