| Notes |
|
| (1) | In this subclass, the functional group which is present already in some residue being introduced and is not substantially involved in a chemical reaction, is not considered as the functional group which is formed or introduced as a result of the chemical reaction. [4] |
|
| (2) | In this subclass, the following term is used with the meaning indicated: |
|
| – | "separation" means separation only for the purposes of recovering organic compounds. [4] |
|
| (3) | In this subclass, in the absence of an indication to the contrary, classification is made in the last appropriate place according to the type of reaction employed, noting the bond or the functional group which is formed or introduced as a result of the chemical reaction. [4] |
|
| (4) | In this subclass, it is desirable to add the indexing codes of subclass C07M. The indexing codes should be unlinked. [6] |
