A set of product information is acquired that describes a first chemical
product that is suitable for a particular use. A second chemical product
that is suitable for the particular use is determined from the set of
product information and a database of chemical product information. It is
determined, from a set of product information that describes a chemical
product and from a database of chemical product information, that
multiple names refer to the same chemical substance. It is determined,
based on product information acquired from an electronic catalog, whether
a database includes information for a chemical substance that is
described in the product information. Based on the determination, at
least a portion of the product information is added to the database.
