Abstract The nomenclature of organic compounds, especially the naming of complex drug molecules, often requires indication of the extra hydrogen and added hydrogen. Their use in Chinese is regulated by the principles for naming organic compounds in the book Nomenclature of Organic Compounds 2017 (CCS 2017), but few specific rules for use and operational examples in it. Based on CCS 2017 and combined with Nomenclature of Organic Chemistry: IUPAC Recommendations and Preferred Names 2013 (IUPAC 2013) and Pharmacopoeia of the People's Republic of China 2020, the concrete implications of extra hydrogen and added hydrogen were explained in detail. The general usage rules and methods for them were illustrated and summarized through the naming of some specific examples. Furthermore, the naming conventions for extra hydrogen and added hydrogen in above three nomenclatures were compared, and their inconsistencies and differences were distinguished. Some suggestions about the application of CCS 2017 principles to the chemical names of drugs were proposed as well.
