Tetraethyl 2,2'-bipyridine-4,4'-bisphosphonate CAS 174397-53-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tetraethyl 2,2'-bipyridine-4,4'-bisphosphonate.

CATO supplies Tetraethyl 2,2'-bipyridine-4,4'-bisphosphonate (CAS 174397-53-6), a certified reference material (molecular formula C18H26N2O6P2, MW 428.36 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, Tetraethyl 2,2'-bipyridine-4,4'-bisphosphonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.36 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
