(E)-2-((2E,4E)-4-(1,3,3-trimethylindolin-2-ylidene)but-2-en-1-ylidene)-2,3-dihydro-1H-inden-1-one 885267-66-3 F9995-0768 (CAS 885267-66-3), molecular formula C24H23NO and molecular weight 341.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-2-((2E,4E)-4-(1,3,3-trimethylindolin-2-ylidene)but-2-en-1-ylidene)-2,3-dihydro-1H-inden-1-one 885267-66-3 F9995-0768 (C24H23NO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
As a certified reference material (CRM), (E)-2-((2E,4E)-4-(1,3,3-trimethylindolin-2-ylidene)but-2-en-1-ylidene)-2,3-dihydro-1H-inden-1-one 885267-66-3 F9995-0768 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.
