Filtering Rules

We have loaded current catalogs from all our suppliers up to 400 Daltons. A few selected catalogs, such as natural products and annotated databases, may have been loaded to 500 and even 600 Daltons in some cases. Molecules are not loaded if:

• They do not pass our generous filtering criteria.
• A failure occurs during processing.

Filtered compounds are now listed on the vendor page, with a justification.
