n-Butylamine (CAS: 109-73-9), also known as 1-aminobutane or mono-n-butylamine (MNBA), is a primary aliphatic amine characterized by a clear, colorless appearance and a pungent, ammonia-like odor. It is a highly versatile organic compound with a molecular formula of $C_4H_{11}N$. Chemically, it is a strong base ($pK_b approx 3.4$) that is fully miscible with water, Alcohol, and ethers. Industrially, it is primarily produced through the catalytic amination of n-butanol or the reductive amination of butyraldehyde.
As a nucleophilic reagent, n-Butylamine is a vital building block in the chemical synthesis of pesticides, pharmaceuticals, and rubber chemicals. Due to its low flash point (-12°C) and high alkalinity, it is classified as a flammable and corrosive liquid (UN 1125). Professional handling requires strict adherence to safety protocols, including the use of explosion-proof equipment and specialized personal protective equipment (PPE) to mitigate risks associated with inhalation and skin contact.
