Chemical Structure
Description
Sulfuric Acid-d2 (96% w/w in D2O) (D2O4S) contains deuterium isotope labeling, a sulfone group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
CATO supplies Sulfuric Acid-d2 (96% w/w in D2O) (CAS 13813-19-9), a certified reference material (molecular formula D2O4S, MW 100.09 g/mol) for analytical method development and quality control.
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.
