 C07
ORGANIC CHEMISTRY (such compounds as the oxides, sulphides, and oxysulphides of carbon, cyanogen, phosgene, hydrocyanic acid and salts thereof C01; macromolecular compounds C08; dyes C09; fermentation products C12; production of organic compounds by electrolysis or electrophoresis C25B 3/00)
 C07

Note(s)

  1. 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 C07C 87/52), sodium oxalate is classified as oxalic acid (in C07C 55/06), 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 C07C and not in sub-class C07F— the alcoholates in C07C 31/28-C07C 31/32 and the phenates as the corresponding phenols in C07C 39/00. Salts formed between two or more organic compounds are classified as the compound providing the essential ion with secondary classification as the compound providing the other ion.
  2. 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 C07C 59/25, 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.
  3. Albumens, proteins, alkaloids of unknown structure, glucosides of unknown structure are examples of compounds to be found unter C07G.
  4. 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.
