List of abbreviations in organic chemistry
This list of abbreviations in organic chemistry lists the most common abbreviations in organic chemistry by subject area. In organic chemistry, abbreviations for very common chemical compounds , reagents , residues and functional groups are used. In addition, some of the abbreviations from biochemistry are also used. In addition to very locally used abbreviations, the laboratory slang, there are a large number of very common abbreviations which are also used without exception in the specialist literature and are therefore included in the list as well as the established ones.
