Chemical Structure
Description
Sodium Hydrosulfide Hydrate (CAS 207683-19-0), molecular formula H2SHSNaH2O and molecular weight 108.15 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula H2SHSNaH2O, Sodium Hydrosulfide Hydrate contains sulfur-containing functionality; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 108.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
