In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1] [2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3] Ideally, every possible organic compound ...
In the IUPAC Nomenclature system, ethers are named using the general formula "alkoxyalkane", for example CH 3 –CH 2 –O–CH 3 is methoxyethane. If the ether is part of a more-complex molecule, it is described as an alkoxy substituent, so –OCH 3 would be considered a "methoxy-" group.

Examples of phenol ethers and their nomenclature. 5-phenoxynonane follows the same naming scheme as 1-phenoxyoctane, due to nonane having more carbons than a benzene ring. When substituents on aromatic rings are present, standard IUPAC nomenclature should be followed when naming aromatic compounds.
Basic IUPAC inorganic nomenclature has two main parts: the cation and the anion. The cation is the name for the positively charged ion and the anion is the name for the negatively charged ion. [14] An example of IUPAC nomenclature of inorganic chemistry is potassium chlorate (KClO 3): Potassium chlorate "Potassium" is the cation name.
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 ...
Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...
In chemical nomenclature, a preferred IUPAC name (PIN) is a unique name, assigned to a chemical substance and preferred among all possible names generated by IUPAC nomenclature. The "preferred IUPAC nomenclature" provides a set of rules for choosing between multiple possibilities in situations where it is important to decide on a unique name.
