Chemical Structure
Description
As a certified reference material (CRM), 3-[(3-Chlorophenyl)amino]-2-phenyl-1H-inden-1-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.
3-[(3-Chlorophenyl)amino]-2-phenyl-1H-inden-1-one (CAS 1020252-39-4), molecular formula C21H14ClNO and molecular weight 331.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-[(3-Chlorophenyl)amino]-2-phenyl-1H-inden-1-one (C21H14ClNO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
