Title: Process and apparatus for comparing chemical products

Abstract: A process and apparatus for comparing chemical products includes a plurality of multi-code groups. Each of the multi-code groups includes a substance code indicating a chemical substance code identifying the product, a specification number code indicating a number of specifications characterizing the chemical substance, and a specification type code indicating the types of specifications, if any, characterizing the chemical substance and/or the attributes, if any, of the chemical substance. The multi-code groups for different products are compared so as to identify similarities and differences between different products based on similarities and differences between corresponding substance codes, specification number codes and specification type codes of the different products.
