Chemical Structure
Description
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.
CATO supplies 85017-77-2 Cobalt(II) bromide hydrate Cobaltous bromide hydrate (CAS 85017-77-2), a certified reference material (molecular formula Br2CoH2O, MW 236.76 g/mol) for analytical method development and quality control.
85017-77-2 Cobalt(II) bromide hydrate Cobaltous bromide hydrate (Br2CoH2O) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
