Chemical Structure
Description
As a certified reference material (CRM), (Z)-3-((5-Methyl-3-(4-nitrophenyl)-1H-pyrrol-2-yl)methylene)indolin-2-one 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.
CATO supplies (Z)-3-((5-Methyl-3-(4-nitrophenyl)-1H-pyrrol-2-yl)methylene)indolin-2-one (CAS 1312226-28-0), a certified reference material (molecular formula C20H15N3O3, MW 345.35 g/mol) for analytical method development and quality control.
The molecular framework of (Z)-3-((5-Methyl-3-(4-nitrophenyl)-1H-pyrrol-2-yl)methylene)indolin-2-one (C20H15N3O3) 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 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.
