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 starting point, that is the time from which these codes are in effect (usually retroactively), varies from group to group, and sometimes from rank to rank. [7] In botany and mycology, the starting point is often 1 May 1753 (Linnaeus, Species plantarum).

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).
Nomenclature (UK: / n oʊ ˈ m ɛ ŋ k l ə tʃ ə, n ə-/, US: / ˈ n oʊ m ə n k l eɪ tʃ ər /) [1] [2] is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences. [3]

A preferred IUPAC name or PIN is a name that is preferred among two or more IUPAC names. An IUPAC name is a systematic name that meets the recommended IUPAC rules. IUPAC names include retained names.
