1,1'-Bis(4-(ethoxycarbonyl)phenyl)-[4,4'-bipyridine]-1,1'-diiumchloride CAS 60095-60-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1'-Bis(4-(ethoxycarbonyl)phenyl)-[4,4'-bipyridine]-1,1'-diiumchloride.

1,1'-Bis(4-(ethoxycarbonyl)phenyl)-[4,4'-bipyridine]-1,1'-diiumchloride (CAS 60095-60-5) is a high-purity analytical reference standard with the molecular formula C28H26N2O4Cl and a molecular weight of 489.98 g/mol.

The molecular framework of 1,1'-Bis(4-(ethoxycarbonyl)phenyl)-[4,4'-bipyridine]-1,1'-diiumchloride (C28H26N2O4Cl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 1,1'-Bis(4-(ethoxycarbonyl)phenyl)-[4,4'-bipyridine]-1,1'-diiumchloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
