Chemical Structure
Description
Owing to a sulfone group, Magnesium sulfate hexahydrate puriss. p.a., ≥99.0% is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Magnesium sulfate hexahydrate puriss. p.a., ≥99.0% (CAS 17830-18-1) is a high-purity analytical reference standard with the molecular formula O4SMgH2O and a molecular weight of 138.38 g/mol.
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.
