ChemDraw needs to be able to assign each stereocenter correctly. We hope to make these recommendations available in our ACD/Name software in the future. 1) Label the structures clearly with a unique name. The full text of these recommendations is available in the print version 1 and in HTML format 2. The majority of the updated IUPAC organic nomenclature recommendations have been implemented in ACD/Name v2015 and later. The most significant change was the concept of “Preferred IUPAC Name” (PIN), established by a hierarchical order of criteria allowing the derivation of a unique systematic name intended for registrations, patents, regulations, etc.Īdditionally, this publication included nomenclature principles developed for more complex substances and new classes of compounds such as fullerenes and cyclophanes. In 2013, a new version of the IUPAC Blue Book was published, which included a variety of changes and new recommendations to keep pace with the growing complexity of chemical substances. The IUPAC Recommendations on the Nomenclature of Organic Chemistry (IUPAC Blue Book) 1 provide naming principles for all classes of organic compounds, and continue to evolve. If you require chemical substance names for reporting to regulatory agencies, they should be manually checked or obtained directly from CAS. * Index naming algorithms have been developed by ACD/Labs alone and CAS makes no warranty or guarantee about its effectiveness or accuracy. Import multiple structures from SDfiles and automatically generate their names.Dynamically display the nomenclature rules used to name your structure.Display a “hierarchical graph” for each stereocenter.Assign stereodescriptors ( R/ S, E/ Z, M/ P, r/ s, seqCis/ seqTrans, α/β, and cis/ trans). ![]()
