nicotinyl

Nicotinyl refers to a chemical moiety or radical derived from nicotinic acid, also known as niacin or vitamin B3. It is a pyridine-3-carboxyl group. In organic chemistry, the term "nicotinyl" is often used to describe substituents or functional groups attached to other molecules. For example, nicotinyl alcohol is a compound where a nicotinyl group is linked to an alcohol.

In pharmacology, derivatives containing the nicotinyl group are of interest. Nicotinyl tartrate, for instance, is a compound that has been used for its vasodilating properties. Another example is nicotinyl alcohol tartrate, also known as xanthinol nicotinate, which is a vasodilator and has been used in some regions for the treatment of peripheral vascular diseases. The nicotinyl group itself is a building block in the synthesis of various pharmaceuticals and organic compounds. Its presence within a larger molecule can influence the compound's properties, including its solubility, reactivity, and biological activity. The core structure of nicotinyl is a pyridine ring with a carboxyl group at the 3-position.
