For the first time, chemists, biochemists, pharmacologists, scientists at all levels in both academia and industry, documentalists, editors, and software developers can rely on a user-friendly book which contains everything required for the construction or interpretation of systematic names of organic, organometallic, or coordination compounds, as well as those for more complicated molecules: Logic, coherent structure and organization of the material according to the procedure of naming, based on the Chemical-Abstracts nomenclature guidelines, with IUPAC recommendations and many trivial names. Detailed description of the names of molecular-skeleton parents, including an illustrative procedure for the naming of fused polycycles. Construction of the names of all compound classes illustrated by colors, with an emphasis on radicals, ions, and organometallic and coordination compounds. Collection of the stereoparent names of the alkaloids, amino acids, peptides, carbohydrates, cylitols, nucleosides, nucleotides, nucleic acids, steroids, terpenes, carotenoides, retinoids, vitamins, and porphyrins as well as guidelines for the naming of polymers and isotopically modifies compounds. For the first time, detailed instructions for the citation of indicated H atom (indicated hydrogen) in names. Comprehensive description of the Cahn-Ingold-Prelog system for the specification of configuration and of the thus derived stereodescriptors for names of chiral organic, organometallic, and coordination compounds, including instructions concerning the stereodescriptors used by Chemical Abstracts until 1999. Over 6000 drawings of compounds with names from practice, about 2700 in color.
