1. INTRODUCTION
The universal adoption of an agreed nomenclature is a key tool for efficient communication in the chemical sciences, in industry and for regulations associated with import/export or health and safety. The International Union of Pure and Applied Chemistry (IUPAC) provides recommendations on many aspects of nomenclature.1 The basics of organic nomenclature are summarized here, and there are companion documents on the nomenclature of inorganic2 and polymer3 chemistry, with hyperlinks to original documents. An overall summary of chemical nomenclature can be found in Principles of Chemical Nomenclature. 4 Comprehensive detail can be found in Nomenclature of Organic Chemistry, colloquially known as the Blue Book,5 and in the related publications for inorganic compounds (the Red Book), 6 and polymers (the Purple Book).7 It should be noted that many compounds may have non-systematic or semi-systematic names and IUPAC rules also allow for more than one systematic name in many cases. Some traditional names (e.g. styrene, urea) are also used within systematic nomenclature. The new edition of the Blue Book5 incorporates a hierarchical set of criteria for choosing the single name which is to be preferred for regulatory purposes, the Preferred IUPAC Name, or PIN.
