Distinguish an identity reference from a certified standard

A record with a CAS identifies the reference compound. It does not, on its own, demonstrate a certified value, stated uncertainty or metrological traceability. Specify what your analytical method requires.

Before an inquiry

  • Analyte, identity and chemical form used by your method.
  • Assigned-value, uncertainty and traceability requirements, where necessary.
  • Batch and analytical evidence available for the specific material.
