The Merck Index Online is a fully-searchable database with over 11,500 monographs on chemicals, drugs, and biologicals. In addition, the Merck Index includes a reference of over 500 named organic reactions and reference tables that include common abbreviations, chemical structures, constants, and conversions.
The new online edition also includes historical records not available in the print edition. In addition, the Merck Index includes a reference of over 500 named organic reactions and reference tables that include common abbreviations, chemical structures, constants, and conversions.
PubChem is a search tool for chemical information, divided into three areas: Compounds, Substances, and BioAssays.
Full entries provide detailed information with the most basic information and general description, the molecular weight and formula, the structure, plus aTable of Contents (ToC) for the full entry, all easily found above the fold. Use the ToC or scroll down to retrieve more advanced information,such as bioactivity results, synonyms, chemical actions, detailed properties, and more. Each module is fully interlinked with the other sections of PubChem as well as resources in ToxNet and PubMed, providing full access to toxicology resources and the medical literature, and allowing users access to as much or as little of the chemical information as they need.
ChemSpider is a free access service providing a structure centric community for chemists. Providing access to millions of chemical structures and integration to a multitude of other online services, ChemSpider is the richest single source of structure-based chemistry information.
