The occurrence of 4,4'-(3,8-Bis((4-aminophenyl)ethynyl)pyrene-1,6-diyl)dibenzaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4'-(3,8-Bis((4-aminophenyl)ethynyl)pyrene-1,6-diyl)dibenzaldehyde (CAS 2375652-85-8), molecular formula C46H28N2O2 and molecular weight 640.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4'-(3,8-Bis((4-aminophenyl)ethynyl)pyrene-1,6-diyl)dibenzaldehyde (C46H28N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 34.0, corresponding to approximately 34 ring(s) or double-bond equivalent(s). With a molecular weight of 640.73 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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'-(3,8-Bis((4-aminophenyl)ethynyl)pyrene-1,6-diyl)dibenzaldehyde 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.
