APPENDIX C – GUIDE FOR SELECTING GENERIC NAMES
This guide describes a procedure for naming hazardous chemicals and the division of substances into families.
The families are defined in the following manner:
    * inorganic or organic substances whose properties are identified by having a common chemical element as their chief characteristic. The family name is derived from the name
      of the chemical element. These families are identified as in subsection C1.3 below by the atomic number of the chemical element (001 to 103)
    * organic substances whose properties are identified by having a common functional group as their chief characteristic.
       * the family name is derived from the functional group name, and
       * these families are identified by the number convention found in subsection C1.3
         (601 to 650).
    * sub-families bringing together substances with a common specific character have been added in certain cases.

Establishing the Generic Name
C.1.  General Principles
In selecting a generic name, the following approach is adopted:
    * identify 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. These names are set out in subsection C.3 in the form of a (non-restrictive) list.
C.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:
     a)      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.
Examples:
Name                  Family                              Generic Name
                       Sub-family
1,4-dihydroxybenzene  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
                       Methacrylates

     b)      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.
Examples:
Name                              Family                                  Generic Name
