Frequent Questions

What is a Registry Name?

The Chemical Identification Data Standard, developed jointly by EPA and its state and tribal partners, requires four identifiers for each chemical. Two of those identifiers are names: Systematic Name and Registry Name. The Registry Name is a common name for a chemical substance. This might be the name by which the chemical is more typically known, such as the name printed in newspaper articles or the name listed as an ingredient in a commercial product.  An example is "Toluene" or "Vinyl acetate".
