In the absence of an indication to the contrary, and with the exception referred to below, a compound is always classified in the last appropriate place in the classification system, e.g. a compound containing an acyclic chain and a heterocyclic ring is classified only as a heterocyclic compound, and a sterol is classified only as a cyclopentanophenanthrene compound. In general, and in the absence of an indication to the contrary (such as groups Fulltext... Hierarchy... Expanded...C07C 59/25, Fulltext... Hierarchy... Expanded...C07C 59/26), the terms "acyclic" and "aliphatic" are used to describe compounds in which there is no ring; and, if a ring were present, the compound would be taken by the "last place" rule to a later group for cycloaliphatic or aromatic compounds, if such a group exists. Where a compound or an entire group of compounds exists in tautomeric forms, it is classified as though existing in the form which is classified last in the system, unless the other form is specifically mentioned earlier in the system.

Inventions dealing with chemical compounds and their preparation are classified in the groups for the type of compound prepared. The processes of preparation should be secondarily classified in the groups for the types of reaction employed when such groups exist. General processes for the preparation of a class of compounds falling into more than one main group are classified in the groups for the processes employed when such groups exist. The compounds prepared may be secondarily classified in the groups for the types of compounds prepared.
