Questions for this material

Which CAS reference applies to this material?

The source sections give 2124-57-4 and 27670-94-6. This page does not choose one as the confirmed identity. Request a corrected specification linking the named material, identity reference and relevant analytical records before quotation or sampling.

Can the 1% listing statement resolve that identity question?

No. An assay statement and an identity reference answer different questions. Confirm the material identity, composition and meaning of the 1% statement in the same written grade specification.
