These are primarily historical in origin, but include the CBS, Evans Aldol and Olefin Metathesis reactions from the 1980s. There are currently 446 Organic Name Reactions. Name Reaction descriptions are detailed and include both the original and recent literature references, as shown above in Figure 1. Organic Name Reactions, knowledge of which is essential for success in both undergraduate and graduate level organic chemistry courses, can be either browsed or keyword searched.
There are more than 4,000 monographs describing drugs and pharmaceuticals, more than 2,000 organic chemicals and reagents, more than 2,000 natural products and plants, more than 1,000 elements and inorganic chemicals, and more than 1,000 compounds in agriculture and several hundred endogenous substances and biological agents. For example, the record for Prozac, which is included with its chemical parent, provides an excellent example of the information available for a variety of research activities.įigure 1: Name Reactions section with literature references. While the number of compounds and substances obviously does not compare with the Combined Chemical Dictionary (500,000), the level of detail in The Merck Index is virtually unique.

This newer version contains all the data that was published in the 13th edition print volume, plus 100 totally new monographs, and 540 monographs that were retired from the 12th edition print volume, resulting in a total of 10,890 monographs.įor most chemists and chemistry librarians, The Merck Index is an obvious first choice for information on chemicals, drugs, and biological substances (based either on current or historical importance and interest). The Merck Index online database is currently in Version 13.2. Coupled with the potential for infinite expandability, the promise of reclaiming older material, that was once deleted from print editions for space reasons, is now being realized.
ONE OF THE NICEST features of an online database is the relative ease of updating. His other interests are politics and history, especially the World War II era. Employed at Caltech since 1965, he served as the Head of Science and Engineering Libraries from 1983-1995 and is currently the chemistry librarian.
