: Pyridines; Pyridine is a six-membered heterocyclic compound containing one nitrogen heteroatom. Pyridine and piperidine are the most frequently occurring heterocyclic building blocks in drug molecules. According to incomplete statistics, there are currently more than 180 drugs containing pyridine or piperidine structure that have been marketed, nearly 1/5 of the drugs approved for marketing in recent years contain these two structures.; Pyridine | C5H5N | Pyridine Supplier/Distributor/Manufacturer - Chemenu; Pyridine,Pyridine Wholesale,Pyridine for Sale,Pyridine Supplier,Pyridine Distributor,Pyridine Manufacturer; Pyridine is a basic heterocyclic organic compound with the chemical formula C5H5N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom. It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish-like smell.

: Tetrahydropyrans; Tetrahydropyran is an organic compound consisting of a saturated six-membered ring containing five carbon atoms and one oxygen atom. Tetrahydropyrans are common structural motifs in natural products and synthetic therapeutic molecules. In nature, these six-membered oxygen heterocycles are usually assembled by intramolecular reactions, including oxygen Michael addition or ring opening of epoxy alcohols. In fact, polyether natural products have been particularly extensively studied for their fascinating structures and important biological properties; these are often formed through endoselective epoxy open cascades.
