Notes

(1)This subclass covers both major and minor chemical modifications.  [3]

(2)Group C12P 1/00 covers processes for producing organic compounds not sufficiently identified to be classified in groups C12P 3/00 to C12P 37/00. Compounds identified only by their empirical formulae are not considered to be sufficiently identified.  [3]

(3)Attention is drawn to Notes (1) to (3) following the title of class C12.  [4]

(4)If a particular reaction is considered of interest, it is also classified in the relevant chemical compound class, e.g. C07, C08.  [3]

(5)In this subclass:

 metal or ammonium salts of a compound are classified as that compound.

 compositions are classified in the relevant compound groups.  [3]

(6)In this subclass, it is desirable to add the indexing codes of subclass C12R. The indexing codes should be linked.  [6]
