A nomenclatura IUPAC é o sistema adequado para nomear compostos químicos, tanto orgânicos quanto inorgânicos (incluindo íons), como prescrito pela International Union of Pure and Applied Chemistry.

Os nomes significam coisas, e o objetivo da IUPAC é certificar-se de que o nome de qualquer substância pura particular seja inequívoco. É claro que, se alguém quiser um identificador único, então um índice numérico será suficiente. O número de registro CAS é o tal índice favorito.

Mas a nomenclatura IUPAC tem um outro objetivo: atribuir a cada substância pura um nome que transmite tanto as proporções dos elementos químicos presentes quanto o arranjo dos átomos desses elementos no nível mais elementar--e mesmo para o comportamento dos elétrons que formam as ligações covalentes que mantêm as moléculas e os íons poliatômicos juntos.

IUPAC nomenclature is by no means perfect, which is why it cannot supplant the CAS registry system altogether. Furthermore, some of the larger, more complex molecules would be very difficult to read or even to pronounce, which is why many organic compounds (especially drugs) are better known by their common or "generic" names.

History of Nomenclature as a Discipline

IUPAC nomenclature by Wikipedia contains a treatment of the history of the development of systematized nomenclature for pure substances. Briefly, this development began in earnest after Antoine Laurent Lavoisier first distinguished elements from compounds, thus recognizing that these are two distinct classes of pure substances.

IUPAC's nomenclature systems

IUPAC has distinct nomenclature systems for organic (carbon-containing) and inorganic (non-carbon-containing) compounds. More broadly, IUPAC publishes a large series of color-coded books that cover various aspects of the naming of pure substances and other quantities important to chemistry.

The Gold Book

The IUPAC Compendium of Chemical Terminology took its common name of "Gold Book" from its first chief editor, Victor Gold. It is a general source book of chemical terminology definitions.

The Green Book

Quantities, Units and Symbols in Physical Chemistry is primarily a dictionary of accepted systems of measurement of physical quantities, and the units of such measurement.

The Red Book

This is IUPAC's definitive dictionary of Nomenclature of Inorganic Chemistry.

The Blue Book

This is IUPAC's definitive dictionary of Nomenclature of Organic Chemistry.

The Purple Book

This is the IUPAC Compendium of Macromolecular Nomenclature. This concerns the naming of molecules of protein size or larger.

The Orange Book

The IUPAC Compendium of Analytical Nomenclature lays down the rules for analytical calculations, beginning with the fundamental precepts behind such calculations.

The Silver Book

The IUPAC Compendium of Terminology and Nomenclature of Properties in Clinical Laboratory Sciences is relatively new to the IUPAC colored-book series. Issued in 1995, it contains recommendations for naming substances and properties in a hospital or other clinical laboratory.

The White Book

This is IUPAC's compendium of Biochemical Nomenclature and Related Documents. The Silver Book is closely related to this publication.
