CAS 110-86-1: Pyridine

Description: Pyridine is a heterocyclic aromatic organic compound characterized by a six-membered ring containing five carbon atoms and one nitrogen atom. Its molecular formula is C5H5N, and it is classified as a basic nitrogen-containing compound. Pyridine is a colorless to yellow liquid with a distinctive, unpleasant odor reminiscent of rotten fish. It is highly soluble in water and polar organic solvents, making it a versatile solvent in various chemical reactions. Pyridine exhibits basic properties due to the lone pair of electrons on the nitrogen atom, allowing it to act as a weak base and a nucleophile. It is commonly used as a precursor in the synthesis of agrochemicals, pharmaceuticals, and dyes, as well as a solvent and reagent in organic chemistry. Pyridine is also known for its role in the formation of various derivatives, which can enhance its chemical reactivity and functional properties. However, it is important to handle pyridine with care, as it is toxic and can cause irritation to the skin, eyes, and respiratory system.
