Establishing the Generic Name

D1.1         General Principles
In selecting a generic name, the following approach is adopted:
    * the most specific generic name must be chosen
    * identity of the functional groups and chemical elements present in the molecule
    * determine the most important functional groups and chemical elements, which contribute to its properties.
The identified functional groups and elements taken into account are the names of the families and sub-families set out in subsection 3 in the form of a (non-restrictive) list.

D1.2         Practical application
After having conducted a search to see if the substance belongs to one or more families or sub-families on the list, the generic name can be established in the following way:
    * If the name of a family or sub-family is sufficient to characterise the chemical elements or important functional groups, this name will be chosen as the generic name. For example:

Name                 Family                              Generic Name
                                   Sub-family
1,4-dihydoxybenzene  604: Phenols and derivatives        Phenol derivative
Butanols             603: Alcohols and derivatives       Aliphatic alcohol
                                   Aliphatic alcohols
2-isopropoxyethanol  603: Alcohols and derivatives       Glycolether
                     Glycolethers
Methacrylate         607: Organic acids and derivatives  Methacrylate
                                   Methacrylate

    * If the name of a family or sub-family is not sufficient to characterise the chemical elements of important functional groups, the generic name should be a combination of the corresponding different family or sub-family names. For example:

Name                              Family                                    Generic Name
                                                sub-family

Note: In the case of certain elements, notably metals, the name of the family or sub-family may be indicated by the words 'organic' or 'inorganic'. For example:

Name                  Family                    Generic Name
                                    sub-family
