At NINGBO INNO PHARMCHEM CO.,LTD., we frequently explore the foundational aspects of organic chemistry, and understanding diamine chemical properties is central to many of our product applications. Today, we focus on 1,8-Diaminooctane (CAS 373-44-4), a prominent example that illustrates the diverse reactivity and utility of these compounds.

1,8-Diaminooctane is characterized by its two primary amine groups, –NH₂, located at opposite ends of an eight-carbon aliphatic chain. This molecular architecture grants it a unique set of physical and chemical properties. Physically, it typically appears as a white to light yellow solid, with a melting point around 50-52°C. Its boiling point is approximately 225-226°C, and it exhibits good solubility in water, dissolving up to 575g/L at 20°C. These properties are critical for its handling and application in various chemical processes.

Chemically, the amine groups in 1,8-Diaminooctane are nucleophilic and basic, making them reactive towards electrophilic reagents. This bifunctionality is key to its role as an organic intermediate. It readily participates in reactions such as:

  • Acylation: Reaction with acid chlorides or anhydrides to form amides.
  • Alkylation: Reaction with alkyl halides to form secondary and tertiary amines.
  • Condensation: Reaction with dicarboxylic acids or their derivatives to form polyamides.
  • Michael Addition: Addition to activated alkenes.

These reactions are fundamental to its use in synthesizing polymers, pharmaceuticals, and agrochemicals. The length of the carbon chain between the amine groups influences the flexibility and properties of the resulting polymers, making 1,8-Diaminooctane a valuable choice for specific material designs.
