71M41949N8 7790-58-1 Potassium tellurate(IV) Dipotassium trioxotellurate Telluric acid, dipotassium salt Telluric acid (H2TeO3), potassium salt (1:2) Telluric acid (H2TeO3), dipotassium salt EINECS 232-213-1 Potassium tellurite UNII-71M41949N8 (CAS 7790-58-1), molecular formula O3TeK and molecular weight 214.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 71M41949N8 7790-58-1 Potassium tellurate(IV) Dipotassium trioxotellurate Telluric acid, dipotassium salt Telluric acid (H2TeO3), potassium salt (1:2) Telluric acid (H2TeO3), dipotassium salt EINECS 232-213-1 Potassium tellurite UNII-71M41949N8 (O3TeK) 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.
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.
