Why search?Physical propertiesMelting point, boiling point, flash point, refractive index, density, solubility data, toxicity data Developing a synthesisExperimental proceduresSpectroscopy dataFTIR, 1H-NMR, 13C-NMR, MS, UV-VISBackground for research
Where search?Reference booksMerck IndexCRC Handbook of Chemistry and PhysicsMarchs Advanced Organic ChemistryArticlesGoogle? Google Scholar?American Chemical Society Publications
The Merck IndexA one-volume encyclopedia of chemicals, drugs and biological compounds Contains more than 10,000 monographsconcise descriptions of a single substance or a small group of closely related compounds First published in 1889Now the standard reference for chemists, biochemists, pharmacologists, pharmacists, and related professionals
Compounds in the Merck IndexHuman and veterinary drugs Biologicals and natural products Plants and herbal medicines Nutraceuticals and cosmeceuticals Agricultural chemicals Industrial chemicals Laboratory reagents and catalysts Dyes, colors and indicators Environmentally significant substances
Information in the Merck IndexChemical, common and generic names Trademarks and associated companies CAS Registry Number Chemical structure Molecular formula and percentage composition Capsule statement identifying compound classes and scientific significanceScientific and patent literature referencesPhysical and toxicity data Therapeutic and commercial uses Caution and hazard information
Also in the Merck IndexIndicesName, Formula, CAS Registry NumberSupplementary tables (some editions)Physical, chemical and biomedical dataListings of pharmaceutical company names and locationsExperimental drug codesOrganic Name Reactions section (some editions) Over 450 reactions featuring descriptions, literature references and graphical depictions
