Descriptions for C12P and notes/indexes are displayed on this screen.


Note(s)
    This subclass covers both major and minor chemical modifications.[3,4,6]Group C12P 1/00 covers processes for producing organic compounds not sufficiently identified to be classified in groups C12P 3/00-C12P 37/00. Compounds identified only by their empirical formulae are not considered to be sufficiently identified.Attention is drawn to Notes (1) to (3) following the title of class C12.If a particular reaction is considered of interest, it is also classified in the relevant chemical compound class, e.g. C07, C08.In this subclass:
      metal or ammonium salts of a compound are classified as that compound;compositions are classified in the relevant compound groups.
    In this subclass, it is desirable to add the indexing codes of subclass C12R.
