Class Information
Number: 987/39
Name: Organic compounds containing a bi, sb, as, or p atom or containing a metal atom of the 6th to 8th group of the periodic system > Phosphorus compounds (9/02; 9/06) > Compound contains a ring which is devoid of a metal atom and contains at least one p atom as ring member (9/6564; 9/6564v; 9/6568; 9/6568b; 9/6568c; 9/6568d; 9/6568e; 9/6568f) > Ring contains o and p only, or may include in addition to the required o and p, only c (9/6571) > Ring contains a p(o) group as atoms within the ring and wherein all atoms bonded to the p atom within the ring, or extracyclic to the ring, are oxygen (9/6574; 9/6574a1)
Description: Subject matter wherein the phosphorus in the ring is bonded solely to oxygen atoms in the ring and solely to oxygen atoms extracyclic to the ring.
