Class Information
Number: 549/369
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Oxygen containing hetero ring (e.g., dioxirane, etc.) > The hetero ring is six-membered > Plural ring oxygens in the hetero ring (e.g., 1,2-dioxin, etc.) > The ring oxygens are in the 1,3-positions of the hetero ring (e.g., 1,3 dioxane, etc.)
Description: Compounds in which the hetero ring consists of two ring oxygens and four ring carbons wherein the ring oxygens are in the 1,3-positions of the hetero ring.
