    The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)

    The Compendium of Analytical Nomenclature is an IUPAC nomenclature book published by the International Union of Pure and Applied Chemistry (IUPAC) containing internationally accepted definitions for terms in analytical chemistry. [1] It has traditionally been published in an orange cover, hence its informal name, the Orange Book.

    The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book [1] [2] and the Red Book, [3] respectively. A third publication, known as the Green Book , [ 4 ] recommends the use of symbols for physical quantities (in association with the IUPAP ), while a fourth, the Gold Book , [ 5 ...

    This procedure, often known as the sequence rules, is the heart of the CIP system. The overview in this section omits some rules that are needed only in rare cases. Compare the atomic number (Z) of the atoms directly attached to the stereocenter; the group having the atom of higher atomic number Z receives higher priority (i.e. number 1).
