Find Basic Information About Your Compound
Excellent databases to find basic information about chemical compounds: molecular weight, CAS Registry numbers and common physical property data.
Extensive database of chemical and physical property data for 13 million organic, inorganic and organometallic substances. Bring up the chemical's substance record, and view the entire record or use the filter to focus on specific data fields. In many cases, you'll get the numeric data and conditions, always with a corresponding reference and link to a journal article.
Combined Chemical Dictionary
Core data (including derivatives) for 540K compounds, including organic compounds and natural products. Includes Dictionary of Organic Compounds, Dictionary of Natural Products, Dictionary of Drugs, and Dictionary of Inorganic and Organometallic Compounds.
