Chemical Structure

(4-(2,3-Dichlorobenzoyl)-1H-pyrrol-2-yl)(4-(3,4-dichlorophenyl)piperazin-1-yl)methanone CAS 477870-31-8 chemical structure

Description

The molecular framework of (4-(2,3-Dichlorobenzoyl)-1H-pyrrol-2-yl)(4-(3,4-dichlorophenyl)piperazin-1-yl)methanone (C22H17Cl4N3O2) 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 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).

(4-(2,3-Dichlorobenzoyl)-1H-pyrrol-2-yl)(4-(3,4-dichlorophenyl)piperazin-1-yl)methanone (CAS 477870-31-8), molecular formula C22H17Cl4N3O2 and molecular weight 497.20 g/mol, is a CATO reference standard with documented purity and traceability.

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), (4-(2,3-Dichlorobenzoyl)-1H-pyrrol-2-yl)(4-(3,4-dichlorophenyl)piperazin-1-yl)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.
