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.
Bis(2-(2-hydroxyethyl)guanidine), sulfuric acid (CAS 1876-16-0), molecular formula C3H9N3OH2O4S and molecular weight 201.20 g/mol, is a CATO reference standard with documented purity and traceability.
Bis(2-(2-hydroxyethyl)guanidine), sulfuric acid (C3H9N3OH2O4S) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
