Pyrans

Heterocyclic pyrans are a class of organic compounds that contain a six-membered heterocyclic, non-aromatic ring consisting of five carbon atoms and one oxygen atom, with two double bonds. Pyrans are valuable intermediates in the synthesis of various chemicals, including pharmaceuticals and agrochemicals. At CymitQuimica, we offer a diverse range of high-quality pyrans to support your research and industrial applications.
