As a certified reference material (CRM), (3E,6E)-3-(2-((E)-1-Heptyl-3,3-dimethylindolin-2-ylidene)ethylidene)-6-(2-((Z)-1-heptyl-3,3-dimethylindolin-2-ylidene)ethylidene)cyclohexane-1,2,4,5-tetraone 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.
(3E,6E)-3-(2-((E)-1-Heptyl-3,3-dimethylindolin-2-ylidene)ethylidene)-6-(2-((Z)-1-heptyl-3,3-dimethylindolin-2-ylidene)ethylidene)cyclohexane-1,2,4,5-tetraone (CAS 1226487-83-7) is a high-purity analytical reference standard with the molecular formula C44H54N2O4 and a molecular weight of 674.91 g/mol.
The molecular framework of (3E,6E)-3-(2-((E)-1-Heptyl-3,3-dimethylindolin-2-ylidene)ethylidene)-6-(2-((Z)-1-heptyl-3,3-dimethylindolin-2-ylidene)ethylidene)cyclohexane-1,2,4,5-tetraone (C44H54N2O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
