Chemical Structure
Description
As a certified reference material (CRM), 1-(2-Phenyl-1H-indol-3-yl)-2-(pyrrolidin-1-yl)ethane-1,2-dione 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.
1-(2-Phenyl-1H-indol-3-yl)-2-(pyrrolidin-1-yl)ethane-1,2-dione (CAS 4747-41-5) is a high-purity analytical reference standard with the molecular formula C20H18N2O2 and a molecular weight of 318.37 g/mol.
The molecular framework of 1-(2-Phenyl-1H-indol-3-yl)-2-(pyrrolidin-1-yl)ethane-1,2-dione (C20H18N2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
