Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1,1'-(Disulfanediylbis(ethane-2,1-diyl))diguanidine sulfate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.43 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.
CATO supplies 1,1'-(Disulfanediylbis(ethane-2,1-diyl))diguanidine sulfate (CAS 91774-54-8), a certified reference material (molecular formula C6H16N6S2H2O4S, MW 334.43 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.
