IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound.The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ethoxymethane). If the oxygen is not attached to the end of the main alkane chain, then the ...
substitutive naming based on parent hydrides (GeCl 2 Me 2 dichlorodimethylgermane) additive naming ([MnFO 3] fluoridotrioxidomanganese) Additionally there are recommendations for the following: naming of cluster compounds; allowed names for inorganic acids and derivatives; naming of solid phases e.g. non-stoichiometric phases
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Article titles for compounds and related topics should reflect how the compound name is commonly written and use Greek letter prefixes if appropriate, e.g. Α-Ketoglutaric acid, using {{DISPLAYTITLE}} to display as α-Ketoglutaric acid, not Alpha-Ketoglutaric acid and displaying as alpha-Ketoglutaric acid.
Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), ...
