Descriptions for C07C and notes/indexes are displayed on this screen.


Note(s)
    In this subclass, the following terms or expressions are used with the meanings indicated:[3,5,7]
      "bridged" means the presence of at least one fusion other than ortho, peri or spiro;two rings are "condensed" if they share at least one ring member, i.e. "spiro" and "bridged" are considered as condensed;"condensed ring system" is a ring system in which all rings are condensed among themselves;"number of rings" in a condensed ring system equals the number of scissions necessary to convert the ring system into one acyclic chain;"quinones" are compounds derived from compounds containing a six-membered aromatic ring or a system comprising six-membered aromatic rings (which system may be condensed or not condensed) by replacing two or four CH groups of the six-membered aromatic rings by —C=O groups, and by removing one or two carbon-to-carbon double bonds, respectively, and rearranging the remaining carbon-to-carbon double bonds to give a ring or ring system with alternating double bonds, including the carbon-to-oxygen bonds; this means that acenaphthenequinone or camphorquinone are not considered as quinones 
    Attention is drawn to Note (3) after class C07, which defines the last place priority rule applied in the range of subclasses C07C-C07K and within these subclasses Therapeutic activity of compounds is further classified in subclass A61P When classifying in this subclass, classification is also made in group B01D 15/08—insofar as subject matter of general interest relating to chromatography is concerned In this subclass, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, a process is classified in the last appropriate place In this subclass, in the absence of an indication to the contrary, "quaternary ammonium compounds" are classified with the corresponding "non-quaternised nitrogen compounds" For the classification of compounds in groups C07C 1/00-C07C 71/00—and C07C 401/00-C07C 409/00:
      a compound is classified considering the molecule as a whole (rule of the "whole molecule approach");a compound is considered to be saturated if it does not contain carbon atoms bound to each other by multiple bonds;a compound is considered to be unsaturated if it contains carbon atoms bound to each other by multiple bonds, which includes a six-membered aromatic ring,
    unless otherwise specified or implicitly derivable from the subdivision, as in group C07C 69/00, e.g C07C 69/712.For the classification of compounds in groups C07C 201/00-C07C 395/00, i.e. after the functional group has been determined according to the "last place rule", a compound is classified according to the following principles:
      compounds are classified in accordance with the nature of the carbon atom to which the functional group is attached;a carbon skeleton is a carbon atom, other than a carbon atom of a carboxyl group, or a chain of carbon atoms bound to each other; a carbon skeleton is considered to be terminated by every bond to an element other than carbon or to a carbon atom of a carboxyl group;when the molecule contains several functional groups, only functional groups linked to the same carbon skeleton as the one first determined are considered;a carbon skeleton is considered to be saturated if it does not contain carbon atoms bound to each other by multiple bonds;a carbon skeleton is considered to be unsaturated if it contains carbon atoms bound to each other by multiple bonds, which includes a six-membered aromatic ring
