| Description | 4-Hydroxy-2H-pyran-3-carboxaldehyde, also known as 3-formyl-4-hydroxy-2H-pyran, belongs to the class of organic compounds known as pyrans. Pyrans are compounds containing a pyran ring, which is a six-member heterocyclic, non-aromatic ring with five carbon atoms, one oxygen atom and two ring double bonds. Based on a literature review very few articles have been published on 4-Hydroxy-2H-pyran-3-carboxaldehyde. |
