How to Use this Library

  • Full & Truncated CAS Number - To obtain an exact Chemical compound enter a full CAS registry number of the compound in the Search box. In the instance where only the truncated part of the CAS registry number is available, enter the truncated part in the search box and you will receive a list of hits with that truncation.

  • Chemical Name Search - Because chemical names vary significantly, chemical name searches are frequently inconclusive. For this reason, our search engine is designed to provide a nested result. For example, if you are searching for an acid and do not know its CAS Number, executing a search with just the term acid in the Search box will result in a list of all available compounds in the Library with the term acid in their name. Likewise, executing a search with the term alpha in the Search box will produce a list of all entries in which this term occurs. Similarly, if the product you are looking for is Pyridine, you can enter the word Pyrid in the search box and you will receive a list of all Pyridines.

  • Molecular Formula - Expressed as CtHxNyOwSz where t, x, y, w, z represent, respectively, the integer corresponding to the number of atoms of that element in the Molecular Formula, for example: C22H32NO2.

Note that, as with a term that is part of the chemical name, e.g., acid as discussed above, you can alternatively enter a truncation of the chemical formula, e.g., NO2, or a truncation of the CAS Number, e.g., -32.

Note, however, that you cannot simultaneously execute a search using two or more truncated terms, e.g. you cannot search for a truncated CAS Number and a truncated chemical name and/or truncated molecular formula. Thus, specifying -32 and NO2 will not return any results even if there is a compound with -32 in the CAS Number and NO2 in the formula.

In addition to searching, you can also filter your results by chemical class by selecting a chemical class from the pull-down. For example, type acid in the search box and then select Lipids from the pull-down to find all Lipid compounds that have acid as part of their name. If you leave the Search Box empty, you can use the chemical class filter to find all compounds in a class.
