Chemical Structure

1-(3,5-Dimethylphenyl)-3,4-bis((2R,5R)-2,5-dimethylphospholan-1-yl)-1H-pyrrole-2,5-dione CAS 1044553-58-3 chemical structure

Description

The molecular framework of 1-(3,5-Dimethylphenyl)-3,4-bis((2R,5R)-2,5-dimethylphospholan-1-yl)-1H-pyrrole-2,5-dione (C24H33NO2P2) is characterized by a steroid core, an amide group, organophosphorus functionality, 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).

1-(3,5-Dimethylphenyl)-3,4-bis((2R,5R)-2,5-dimethylphospholan-1-yl)-1H-pyrrole-2,5-dione (CAS 1044553-58-3), molecular formula C24H33NO2P2 and molecular weight 429.47 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), 1-(3,5-Dimethylphenyl)-3,4-bis((2R,5R)-2,5-dimethylphospholan-1-yl)-1H-pyrrole-2,5-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.
