Chemical Structure
Description
The molecular framework of 4,4',4",4"'-(Pyrene-1,3,6,8-tetrayl)tetrakis(2-aminobenzoic acid) (C44H30N4O8) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4,4',4",4"'-(Pyrene-1,3,6,8-tetrayl)tetrakis(2-aminobenzoic acid) (CAS 2225888-66-2), molecular formula C44H30N4O8 and molecular weight 742.73 g/mol, is a CATO reference standard with documented purity and traceability.
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), 4,4',4",4"'-(Pyrene-1,3,6,8-tetrayl)tetrakis(2-aminobenzoic acid) 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.
