CATO supplies 4,4'-(((9H-fluorene-9,9-diyl)bis(4,1-phenylene))bis(azanediyl))bis(4-oxobutanoic acid) (CAS 457922-91-7), a certified reference material (molecular formula C33H28N2O6, MW 548.59 g/mol) for analytical method development and quality control.

The molecular framework of 4,4'-(((9H-fluorene-9,9-diyl)bis(4,1-phenylene))bis(azanediyl))bis(4-oxobutanoic acid) (C33H28N2O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
