Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,2',2'',2'''-(Hydrazine-1,1,2,2-tetrayl)tetrakis(ethan-1-ol) (CAS 55467-91-9), a certified reference material (molecular formula C8H20N2O4, MW 208.26 g/mol) for analytical method development and quality control.
2,2',2'',2'''-(Hydrazine-1,1,2,2-tetrayl)tetrakis(ethan-1-ol) (C8H20N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl 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.
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.
