Note(s) Anhydrides and halides of carboxylic acids are classified as the relevant acids unless otherwise indicated. Salts of a compound, unless specifically provided for, are classified as that compound, e.g. aniline hydrochloride is classified as containing carbon, hydrogen and nitrogen only (in Fulltext... Hierarchy... Expanded...C07C 87/52), sodium malonate is classified as malonic acid (in Fulltext... Hierarchy... Expanded...C07C 55/08), and a mercaptide is classified as the mercaptan. Metal chelates are dealt with in the same way. Similarly, metal alcoholates and metal phenates are classified in sub-class Fulltext... Hierarchy... Expanded...C07C and not in sub-class Fulltext... Hierarchy... Expanded...C07F— the alcoholates in Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...C07C 31/28-C07C 31/32 and the phenates as the corresponding phenols in Fulltext... Hierarchy... Expanded...C07C 39/235 or Fulltext... Hierarchy... Expanded...C07C 39/44. Salts or adducts formed between two or more organic compounds are classified according to all compounds forming the salts or adducts. [2] In the absence of an indication to the contrary, and with the exception referred to below, a compound is classified in the last appropriate place, e.g. a compound containing an acyclic chain and a heterocyclic ring is classified only as a heterocyclic compound, and a steroid 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 59/58, Fulltext... Hierarchy... Expanded...C07C 59/70), 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. Albumens, proteins, alkaloids of unknown structure, glucosides of unknown structure are examples of compounds to be found unter Fulltext... Hierarchy... Expanded...C07G. 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.
