IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
3 COOH, which is commonly called acetic acid and is also its recommended IUPAC name, but its formal, systematic IUPAC name is ethanoic acid. 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 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. A general IUPAC name is any IUPAC name that is not a "preferred IUPAC name". A retained name is a traditional or otherwise often used name ...
A full edition was published in 1979, [1] an abridged and updated version of which was published in 1993 as A Guide to IUPAC Nomenclature of Organic Compounds. [2] Both of these are now out-of-print in their paper versions, but are available free of charge in electronic versions.
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
