DEFINITION

Classification: 514/238.8

Chalcogen attached indirectly to the morpholine ring by acyclic nonionic bonding:

(under subclass 231.2) Subject matter in which the morpholine ring is attached indirectly to chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) by acyclic nonionic bonding.
