Alphabetical compound name index

The number of organic compounds is virtually limitless. Each needs a name that can be used in discussing the compound or writing about it. Furthermore, it is often necessary to look up the properties of a compound. (You should find out the physical properties of all the compounds that you use in the laboratory.) Very large tables of compounds and indexes use alphabetical listings of compound names. 

There are three printed indexes a name index which lists every compound name or synonym in alphabetical order a molecular formula index which lists all molecular formulae, including those of derivatives, in Hill convention order and a CAS registry number index listing all CAS numbers included in the Sourcebook in serial order. All indexes refer to the entry number. In the name index an entry number which follows immediately upon an index term means that the term itself is used as the entry name but an entry number which is preceded by the word see means that the term is a synonym to an entry name. In all three indexes an entry number which is preceded by the word in refers the reader to a specified stereoisomer or derivative which is to be found embedded within the particular entry. 

All the systematic CA Index Names - with references to the corresponding Ring File Numbers - are listed alphabetically in the Ring Name Index (Fig. 75). In this case, as they are only the names of parent compounds, inversion of the CA Index Names is impossible. 

Both common and systematic names of compounds are used throughout this volume, depending on which the Editor-in-Chief feels is most appropriate. Preparations appear in the alphabetical order of names of the compound or names of the synthetic procedures. The Chemical Abstracts indexing name for each title compound, if it differs from the title name, is given as a subtitle. Because of the major shift to new systematic nomenclature adopted by Chemical Abstracts in 1972, many common names used in the text are immediately followed by the bracketed, new names. Whenever two names are concurrently in use, the carre CChemical Abstracts name is adopted. The prefix n- is deleted from -alkanes and w-alkyls. All reported dimensions are now expressed in S st me International units. 

Preparations appear in the alphabetical order of common names of the compounds. Eor convenience in surveying the literature concerning any preparation through Chemical Abstracts subject indexes, the Chemical Abstracts indexing name for each compound is given as a subtitle if it differs from the common name used as the title. 

Compounds which are considered to be unusually hazardous in a fire context because of their low flash points (below 25°C) or auto-ignition temperatures (below 225°C) are included in the table. The names used are those titles in the text of Section 1 which are prefixed with a dagger. Synonyms may be found either in Section 1 or in the alphabetical index of chemical names and synonyms in Appendix 4. Boiling points are given for those compounds boiling below 50°C. 

A single unstable compound of known composition is placed in the main first volume and is located on the basis of its empirical molecular formula expressed in the Hill system used by Chemical Abstracts (C and H if present, then all other element symbols alphabetically). The use of this indexing basis permits a compound to be located if its structure can be drawn, irrespective of whether a valid name is known for it. A representation of the structure of each compound is given on the third bold title line while the name of the compound appears as the first bold title line. References to the information source are given, followed by a statement of the observed hazard, with any relevant explanation. Cross-reference to similar compounds, often in a group entry, completes the entry. See Trifluoroacetyl nitrite p. 244.
