There are two main areas:
- IUPAC nomenclature of inorganic chemistry (Red Book)
- IUPAC nomenclature of organic chemistry (Blue Book)
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
