Merck Index

First issue, titled Merck's Index

The Merck Index is an encyclopedia of chemicals, drugs and biologicals with over 10,000 monographs on single substances or groups of related compounds published online by the Royal Society of Chemistry.

History

The NFL edition of the Merck's Index was published in 1889 by the German chemical company Emanuel Merck and was primarily used as a sales catalog for Merck's growing list of chemicals it sold. The American subsidiary was established two years later and continued to publish it. During World War I the US government seized Merck's US operations Merck & Co., forming a separate American company that continued to publish the Merck Index.

In 2012 the Merck Index was licensed to the Royal Society of Chemistry. An online version of The Merck Index, including historic records and new updates not in the print edition, is commonly available through research libraries. It also includes an appendix with monographs on organic named reactions.

The 15th edition was published in April 2013.

Monographs in The Merck Index typically contain:

• a CAS registry number
• synonyms of the substance, such as trivial names and International Union of Pure and Applied Chemistry nomenclature
• a chemical formula
• molecular weight
• percent composition
• a structural formula
• a description of the substance's appearance
• melting point and boiling point
• solubility in solvents commonly used in the laboratory
• citations to other literature regarding the compound's chemical synthesis
• a therapeutic category, if applicable
• caution and hazard information
