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.
Magnesium sulfate heptahydrate (CAS 10034-99-8), molecular formula O4SMgH2O and molecular weight 138.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Magnesium sulfate heptahydrate (O4SMgH2O) 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.
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.
