Asystematic name is a name given in a systematic way to one unique group, organism, object orchemical substance, out of a specific population or collection. Systematic names are usually part of anomenclature.
Asemisystematic name orsemitrivial name is a name that has at least one systematic part and at least onetrivial part,[1][2] such as a chemicalvernacular name.
Creating systematic names can be as simple as assigning aprefix or a number to each object (in which case they are a type ofnumbering scheme), or as complex as encoding the complete structure of the object in the name. Many systems combine some information about the named object with an extra sequence number to make it into aunique identifier.
Systematic names often co-exist with earlier common names assigned before the creation of any systematic naming system. For example, many common chemicals are still referred to by their common or trivial names, even by chemists.
In chemistry, a systematic name describes the chemical structure of achemical substance, thus giving some information about its chemical properties.
TheCompendium of Chemical Terminology published by theIUPAC defines systematic name as "a name composed wholly of specially coined or selected syllables, with or without numerical prefixes; e.g. pentane, oxazole."[3] However, when trivial names have become part ofchemical nomenclature, they can be the systematic name of a substance or part of it. Examples for some systematic names that have trivial origins arebenzene (cyclohexatriene) orglycerol (trihydroxypropane).
There are standardized systematic or semi-systematic names for:
