IUPAC Color Books

The IUPAC Color Books are the world’s authoritative resource for chemical nomenclature, terminology, and symbols. Terminology definitions published by IUPAC are drafted by international committees of experts in the appropriate chemistry sub-disciplines, and ratified by IUPAC’s Interdivisional Committee on Terminology, Nomenclature and Symbols (ICTNS). The books in this series are as follows:

• Green Book: Quantities, Units and Symbols in Physical Chemistry
• Red Book: Nomenclature of Inorganic Chemistry
• Blue Book: Nomenclature of Organic Chemistry
• Purple Book: Compendium of Polymer Terminology and Nomenclature
• Orange Book: Analytical Nomenclature
• Silver Book: Compendium of Terminology and Nomenclature of Properties Clinical Laboratory Sciences
• White Book: Biochemical Nomenclature
• Gold Book: Chemical Terminology
