👉 Nitriles are organic compounds that contain nitrogen and have a linear structure. They are commonly found in natural sources such as soil, water, and plants and can be classified into two main types: polyamines (such as spermidine) and polynuclear anthraquinones (such as naphthoquinones). Nitriles are important for the synthesis of other organic compounds, including proteins, hormones, and neurotransmitters.
