Yttrium-90 Solution SRM 4427H SDS – National Institute of Standards and Technology (NIST)
Collected by RESDS. Original publisher PDF retained. NIST SRM 4427H: yttrium-90 in 0.1 M (0.4%) hydrochloric acid, 5 mL in a sealed ampoule. Radioactive standard solution, not elemental yttrium metal. Section 3 discloses trace yttrium chloride; its concentration is not restated here because the source table contains overlapping values. The SDS lists yttrium-90 CAS as not applicable and does not state yttrium chloride CAS. Ingredient CAS: hydrochloric acid 7647-01-0; water 7732-18-5. Original issue: 04 October 2018. Distinct SRM identifier from 4427L; use the SDS matching the actual product. Source: NIST. Reuse basis: https://www.nist.gov/copyrights-disclaimers. Original PDF and all page text retained unchanged.
