rel-2,2'-((1E,1'E)-(((1R,2S)-1,2-Di-p-tolylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol CAS 58520-37-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-2,2'-((1E,1'E)-(((1R,2S)-1,2-Di-p-tolylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol.

CATO supplies rel-2,2'-((1E,1'E)-(((1R,2S)-1,2-Di-p-tolylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol (CAS 58520-37-9), a certified reference material (molecular formula C30H28N2O2, MW 448.56 g/mol) for analytical method development and quality control.

The molecular framework of rel-2,2'-((1E,1'E)-(((1R,2S)-1,2-Di-p-tolylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol (C30H28N2O2) 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.

As a certified reference material (CRM), rel-2,2'-((1E,1'E)-(((1R,2S)-1,2-Di-p-tolylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol 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.
