DEFINITION

Classification: 564/348

(under subclass 347) Compounds wherein the chain contains an

- OH bonded to carbon wherein the H of the - OH may be replaced by a substituted or unsubstituted ammonium ion by a Group IA or IIA light metal or an ether group as substituted and there in no amino nitrogen between this group and the ring or ring system.
