Abstract: 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.
