Chemical Structure
Description
Rhenium(IV) oxide dihydrate (CAS 12192-28-8) is a high-purity analytical reference standard with the molecular formula ReH2OO and a molecular weight of 220.22 g/mol.
The molecular framework of Rhenium(IV) oxide dihydrate (ReH2OO) is characterized by an inorganic composition. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
