Chemical Structure
Description
CATO supplies Rubidium hydroxide hydrate (CAS 12026-05-0), a certified reference material (molecular formula RbH2OHO, MW 120.49 g/mol) for analytical method development and quality control.
The molecular framework of Rubidium hydroxide hydrate (RbH2OHO) 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.
