1,1'-Bis(2-phosphonoethyl)-[4,4'-bipyridine]-1,1'-diium chloride CAS 151538-79-3

Description

The occurrence of 1,1'-Bis(2-phosphonoethyl)-[4,4'-bipyridine]-1,1'-diium chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,1'-Bis(2-phosphonoethyl)-[4,4'-bipyridine]-1,1'-diium chloride (CAS 151538-79-3), a certified reference material (molecular formula C14H20N2O6P2Cl, MW 409.72 g/mol) for analytical method development and quality control.

1,1'-Bis(2-phosphonoethyl)-[4,4'-bipyridine]-1,1'-diium chloride (C14H20N2O6P2Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

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.
