Heterocycles with Nitrogen (N)

Heterocycles with Nitrogen (N)

In this category, you will find a wide variety of nitrogen-containing heterocycles. Heterocycles are carbon chains that form a cycle in which at least one position is occupied by a heteroatom, in this case, nitrogen. These compounds are integral in the synthesis of pharmaceuticals, agrochemicals, and dyes, offering unique reactivity and stability. At CymitQuimica, we provide a comprehensive selection of high-quality nitrogen-containing heterocycles to support your research and industrial applications
