Description

Compared with other compounds in its class, the molecular weight of 256.38 g/mol gives (1R,2R)-1,2-Bis(2-hydroxyphenyl)ethylenediamine (1R,2R)-1,2-Diamino-1,2-bis(2-hydroxyphenyl)ethane 2,2'-[(1R,2R)-1,2-Diaminoethylene]bisphenol 870991-70-1 B3012 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1R,2R)-1,2-Bis(2-hydroxyphenyl)ethylenediamine (1R,2R)-1,2-Diamino-1,2-bis(2-hydroxyphenyl)ethane 2,2'-[(1R,2R)-1,2-Diaminoethylene]bisphenol 870991-70-1 B3012 (CAS 870991-70-1), molecular formula C14H28N2O2 and molecular weight 256.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1R,2R)-1,2-Bis(2-hydroxyphenyl)ethylenediamine (1R,2R)-1,2-Diamino-1,2-bis(2-hydroxyphenyl)ethane 2,2'-[(1R,2R)-1,2-Diaminoethylene]bisphenol 870991-70-1 B3012 (C14H28N2O2) is characterized by an amide group, a carboxylic acid 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (1R,2R)-1,2-Bis(2-hydroxyphenyl)ethylenediamine (1R,2R)-1,2-Diamino-1,2-bis(2-hydroxyphenyl)ethane 2,2'-[(1R,2R)-1,2-Diaminoethylene]bisphenol 870991-70-1 B3012 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.
