DEFINITION

Classification: 987/194

Contains the structure (N)-P-(X-C) wherein X is a chalcogen atom, i.e., esteramides (9/24):

(under subclass 187) Subject matter wherein the phosphorus compound contains the structure (N)-P-(X-C) where at least one N atom and chalcogen atom are directly bonded to the P atom and a C atom is directly bonded to the X atom, X is chalcogen.
