List of abbreviations in organic chemistry

from Wikipedia, the free encyclopedia

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.

solvent

Very common solvents are often abbreviated to keep the reaction equations clear.

Chemical compounds are often abbreviated because of their molecular complexity. The abbreviations go e.g. T. without transition to biochemistry. Usually, only the unnatural compounds are named with a stereochemical prefix in the case of chiral compounds .
