The occurrence of (6-(Indolin-1-yl)-2-methylpyridin-3-yl)(phenyl)methanone is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(6-(Indolin-1-yl)-2-methylpyridin-3-yl)(phenyl)methanone (CAS 1355177-41-1), molecular formula C21H18N2O and molecular weight 314.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (6-(Indolin-1-yl)-2-methylpyridin-3-yl)(phenyl)methanone (C21H18N2O) 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), (6-(Indolin-1-yl)-2-methylpyridin-3-yl)(phenyl)methanone 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.
