Review and provenance
The supplier associates this chemical form with an element-family SDS. The PDF does not establish applicability to a particular isotope enrichment or batch.
One webpage application mentions Antimony-122 but repeats Sb-121 aliases. That inconsistent statement is not reproduced as a verified isotope-production relationship.
