According to ISO 257 Pesticides and other agrochemicals – Principles for the selection of common names common names for simple esters and salts should be assigned to the parent acid, alcohol or base when the biological activity derives from the parent. The identity of the simple anion, cation, or radical is then indicated by adding a modifier to the common name.
Multiplicative affixes are used when they are necessary to avoid ambiguity.
For simple anions, cations and radicals, traditional names are used as modifiers for common names. They are also used for some less simple substances, when more systematic names would include locants and the traditional names are unambiguous. For example:
Traditional name | Systematic name | Example |
---|---|---|
butyrate | butanoate | bromoxynil butyrate |
choline | 2-hydroxy-N,N,N-trimethylethan-1-aminium | triclopyr-choline |
diethylammonium | N-ethylethanaminium | 2,4-D-diethylammonium |
dimethylammonium | N-methylmethanaminium | dichlorprop-dimethylammonium |
ethylammonium | ethanaminium | dichlorprop-ethylammonium |
fumarate | (2E)-2-butenedioate | oxpoconazole fumarate |
isobutyl | 2-methylpropyl | mecoprop-P-isobutyl |
isopropyl | 1-methylethyl (= propan-2-yl) | benthiavalicarb-isopropyl |
isopropylammonium | propan-2-aminium | dicamba-isopropylammonium |
laurate | dodecanoate | pentachlorophenyl laurate |
methylammonium | methanaminium | chloramben-methylammonium |
oleate | (9Z)-octadec-9-enoate | copper oleate |
propargyl | prop-2-ynyl | chlorazifop-propargyl |
triethylammonium | N,N-diethylethanaminium | triclopyr-triethylammonium |
The chemical names of some relatively simple substances can be more complicated than is desirable in a common name, and so recommended names were developed or adopted for some of the more frequently occurring ions and radicals and published in ISO 257:2004 (edition 3). These names are listed in the following table and should be used as modifiers for common names in place of the chemical names.

† Adopted WHO INN modifier
There is a separate index of simple salts and esters, and they are also listed in the Notes field of the data sheets of their parent compounds. Their IUPAC systematic names, CAS systematic names, CAS Registry Numbers, molecular formulae and InChIKeys are included in the indexes.
