Cyclohexanamine (MF: C₆H₁₁NH₂, MW: 99.18) is a significant organic amine compound. Possessing both an alicyclic ring (cyclohexyl) and an amino group (-NH₂) in its molecular structure, it combines the stability of alicyclic compounds with the chemical reactivity of amines. Exhibiting strong basicity, it readily undergoes substitution reactions and is susceptible to oxidation. As a crucial intermediate in organic synthesis and fine chemicals, it serves numerous industrial applications.
