Chemical Lab Reporting

Database of critically-evaluated physical property data from collections maintained by the National Institute of Standards (NIST) Standard Reference Data Program and outside contributors. [Allows structure searching.]

Information on specific chemicals, emphasizing biological activities of small molecules. Link to PubMed scientific literature, NCBI's protein 3D structure resource and PubChem's bioassay database. From the National Center for Biotechnology Information.

Sales information, but also basic property data (including, often, various spectra) and key references to other important data resources, including the Beilstein Handbuch. Search in the top right. [Allows structure searching.] Link to Materials Data Safety Sheets.

This WikiProject is meant to standardize information about chemicals found on Wikipedia and to improve the quality of the information available. A compounds rating indicates how reliable the information is. For example, for the over 8000 compounds found in Wikipedia, nearly 2500 are unassessed, meaning the information cannot be verified. Common compounds may have reliable info, but it is best to verify the data found with another source listed above, especially for more uncommon substance.

WA contains a wide variety of data on many chemical compounds. However, WA's major flaw is that it DOES NOT tell you the specific source of the data presented. WA claims to have a proprietary database of data gathered from various sources. While these sources are often listed, you can not be certain where a particular boiling point or heat capacity came from. When you need to cite an exact source or justify your data from a reliable & credible source, try one of the other resource above instead.
