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 Aminoguanidine hemisulfate hydrate (CAS 5959-63-7), a certified reference material (molecular formula H2O4SCH6N4H2O, MW 190.17 g/mol) for analytical method development and quality control.
Owing to a sulfone group, Aminoguanidine hemisulfate hydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
