Chemical products can be searched by:

• Product names
• Molecular formulas
• Catalog numbers
• CAS registry numbers

At this time, equipment, supplies, and books can not be searched. Please contact us to inquire after these items. Matching compounds are displayed in the same order they are printed in the catalog. At this time, hits are not sorted by quality.

Wildcards are allowed in the search text.

• The question mark (?) or underscore (_) characters match any single character.
• The asterisk (*) or percent (%) characters match any number of characters (including zero characters).

When searching for chemicals by name, positional locants and stereochemical designations are ignored and can be omitted. Search by entering one or more name fragments. For example:

• To find Carbobenzyloxy protected amino acids, enter "CBZ amino acid". (Single-letter terms are ignored so the equivalent search "Z amino acid will fail).
• To find p-nitro-L-phenylalanine, enter "nitrophenylalanine".
• To find chlorinated carboxylic acids enter "chloro acid"

If you are unable to find any compound with our search tool, please email us with the details of your search and we will improve it.
