Class Information
Number: 558/164
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Phosphorus esters (i.e., compounds having the phosphorus ester group, wherein trivalent or pentavalent phosphorus and carbon are bonded directly to the same divalent chalcogen, and wherein the carbon may be single bonded to any atom but may be multiple bonded only to carbon) > Plural phosphori attached directly or indirectly to each other by nonionic bonding > Plural phosphorus ester groups > Divalent chalcogen double bonded directly to pentavalent phosphorus > Plural phosphori attached indirectly to each other by an acyclic chalcogen containing chain > Plural chalcogens in the acyclic chain
Description: Compounds in which there are two or more chalcogens (i.e., oxygen, sulfur, selenium, or tellurium) in the acyclic chain.
