Erbium(III) sulphate dihydrate CAS 20814-10-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Erbium(III) sulphate dihydrate (CAS 20814-10-2) is a high-purity analytical reference standard with the molecular formula ErO4SH2O and a molecular weight of 281.33 g/mol.

The molecular framework of Erbium(III) sulphate dihydrate (ErO4SH2O) is characterized by a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

CATO manufactures Erbium(III) sulphate dihydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
